- PURCHASING AND UPGRADING A PC
- YOU'RE ON THAT SINFUL PATH!
-
- ----------------------------------------------------------------
-
- This section includes notes on purchasing both standard sized
- desktop computers as well as the newer laptop computers.
-
- Buying a new or used computer is always THE traumatic event. It
- seems to be easier if you merely NEED one for a definite office
- or productivity goal such as financial analysis or compiling a
- mailing list of customers. In that case, you can be logical and
- evaluate among several machines and take your time. If, however
- you WANT one because it sounds interesting and you feel a little
- lost when everyone in the neighborhood is discussing CPU WAIT
- STATES, you have some serious research ahead!
-
- From a use standpoint, start at the beginning: What do you want
- to do with the computer? What software applications will perform
- these tasks? After determining answers to those two questions,
- purchase as much computing power as you can afford which allows
- you to use all current software of interest as well as retaining
- the possibility of upgrading the machine later - more memory or a
- better video display, for example.
-
- Simple applications like word processing, accounting and
- telecommunications may run equally fast on both budget and high
- end computers while sophisticated software such as drafting,
- large databases and desktop publishing may run so slowly on a
- low end computer that your wasted time far offsets the original
- savings on the budget computer. When in doubt run several
- software packages which provide features you want on the
- computer in question.
-
- Three technical factors are of interest when purchasing a
- computer: the type of CPU (central processing unit) which is the
- brains of a personal computer, the speed of the CPU and finally
- the choice between 8 bit and 16 bit CPU types.
-
- A brief refresher course taken from our PC-Learn introduction.
- A bit is a binary digit used by computers to store and process
- data. Typically 8 bits are needed to construct a byte or
- computer character such as a number or letter. Eight bit
- processors can process one byte or character at a time. Sixteen
- bit processors can processor two bytes at a time.
-
- In the IBM world of clone PC's there are four camps of CPU desire
- and capability.
-
- On the low end of price and performance are personal computers
- of the so-called XT class using the oldest processors such as
- the Intel 8088 (8 bit data bus outside the CPU and 16 bit data
- bus inside the CPU) which was used on the original IBM PC. The
- Intel 8086 CPU, alternatively, provides both 16 bit internal and
- external construction. A similar CPU is the NEC V-20 chip.
- Advantages, disadvantages and uses for these XT class machines?
-
- XT's are affordable. A basic machine with a couple of floppy
- drives, monitor and keyboard can be obtained for $300 to $400.
- XT class machines are useful for small and home office work or
- light hobbyist use such as word processing and accounting where
- speed is not of great concern. Generally XT class machines, as
- with all IBM clones, can be upgraded by the gradual (or
- immediate) addition of hard drives, color monitors and even
- faster processors. As a curious aside, PC-LEARN is programmed
- and edited entirely on an XT class machine. In a sense computing
- power does not derive from the machine, but HOW you use it!
-
- When is an XT not a good buy? If you intend to do CAD drafting,
- work with large database mailing list, or high resolution
- graphics, an XT is not a wise choice. If you ever to run
- the OS/2 operating system or Microsoft Windows which are
- advanced operating and display standards, XT machines are not a
- good idea. Finally, if you intend to expand the machine to
- color graphics such as an EGA or VGA standard or install large
- amounts of memory an XT is probably not an ideal choice.
-
- One step up the ladder in performance and price is the AT class
- machine which runs an Intel (or alternate manufacturer) 80286
- CPU chip. The machine is usually 2 to 4 times faster than an XT
- class machine at perhaps $200 more in price. For most people an
- AT class machine is a comfortable choice since it can not only
- run OS/2 and Windows (albeit sluggishly) but also run earlier
- software programs at greater speeds. AT class machines are
- considered a "plain vanilla" standard in most office environments
- and are usually sold with hard drives and additional memory as
- standard equipment.
-
- The 80286 processor also operates in two modes which the 8088
- and 8086 cannot: REAL MODE which allows the 80286 CPU to work
- like an 8088 CPU and PROTECTED MODE which allows access to more
- RAM memory. In theory, the older 8088 CPU chip can address up to
- 1 Megabyte of memory. An 8088 CPU always operates in real mode.
-
- In protected mode, however, the 80286 CPU can use up to 16
- Megabytes of memory which can be an advantage in running both
- larger, more sophisticated programs as well as earlier programs.
- In addition, the 80286 CPU can, with the proper software, run
- several programs simultaneously which is know as MULTITASKING.
-
- The benefits of both protected mode and multitasking are
- somewhat unrealized at present although certain of these
- benefits can be obtained when running Windows software rather
- than DOS. Because of this, most users who continue to run DOS
- use an 80286 computer as a FAST device rather than seeking the
- advantages of multitasking or protected mode operation. And the
- 80286 is VERY fast indeed with some manufacturers pushing the
- CPU to speeds of 25 Mhz.
-
- Generally, adding additional upgrade equipment such as EGA
- monitors and laser printers is a good investment with an AT
- machine but a poor idea with an XT machine. The AT machine uses
- a 16 bit bus structure for rapid data flow while the older XT
- class machine uses a more primitive 8 bit bus.
-
- AT class machines run graphics and CAD programs relatively
- quickly. Hard drives operate quickly on an AT class machine with
- its larger 16 bit bus. For most folks an AT will last quite a
- few years and expand nicely with extra peripherals as time goes
- on. It is a good choice for the small home office doing word
- processing, accounting, light desktop publishing, medium sized
- database mailing lists and so forth.
-
- Still higher up the food chain are 80386 and 80386SX CPU
- equipped machines which are still faster and provide a few more
- whistles and bells. They can run software which XT and AT class
- machines run, only FASTER. They are the machines of choice for
- office LAN networks, intensive graphics, CAD programming,
- Windows, OS/2, compilers and other number intensive programs.
-
- Curiously, though, the 80386 data bus remains 16 bits wide in
- most of these machines and there is no "OS/3" operating system,
- so the performance you derive is speed without additional
- whistles and bells. For most users, a "386" machine is mostly an
- office computer which a home or hobby user might admire but
- rarely need.
-
- Intel corrected the problem of switching from real mode to
- protected mode - a design flaw of the 80286 - and added a third
- mode called virtual mode which allows the CPU to act as if
- several "separate" 8088 computers are all running within one
- machine. In addition the 80386 chip is a true 32 bit CPU which
- processes four bytes or characters at a time. This 32 bit
- structure effectively makes the 80386 CPU twice as fast as the
- 80286 CPU. Finally, the 80386 can directly address a whopping
- four gigabytes of memory if available which is 256 times larger
- than the amount of memory the 80286 can address! The downside is
- that many of these advantages cannot be realized when running
- DOS. Windows or OS/2 operating systems provide access to these
- advanced features. Speed and additional memory capability is the
- primary byproduct of operating an 80386 within a DOS environment.
-
- The 80386SX is an affordable variant of the 80386 CPU. The key
- difference is that it uses an EXTERNAL 16 bit data bus outside
- the CPU which is similar to that used on conventional 80286 or
- AT class computers. Internally it is quite similar to its big
- brother, the 80386, and offers similar multitasking modes and
- memory addressing. It can run all of the software the 80386
- machine can, albeit slightly more slowly. These design
- compromises allow manufacturers to produce an affordable
- computer with a good balance of speed and cost. For many users
- needing a powerful computer which can run all current and most
- future software, the 80386SX is an enviable balance of
- performance versus price and offers superior memory management,
- optimum speed and ability to run current and future software.
-
- The primary reason to select a 80386 over the 80386SX involves
- the need for higher speed processing, ability to run 32-bit
- software and advanced multitasking.
-
- Before introducing the fourth Intel CPU, the 80486, two new
- concepts must be mentioned: memory caching and mathcoprocessing.
-
- As the speed of the CPU becomes faster, the RAM memory chips
- where data is stored have difficulty moving data into and out of
- the CPU. Memory caching involves special high speed RAM memory
- chips - typically an amount from 64K to 128K - in addition to
- the normal memory chips within the computer. These high speed
- chips are expensive but keep data poised to quickly move in and
- out of the CPU. Memory caching should not be confused with disk
- caching which is another concept used when discussing hard
- drives.
-
- A second way to increase performance is to install a math
- coprocessor chip into the empty socket which is available on
- most computers. This device shares the processing of specific
- numeric operations which can slow the CPU. Only certain types of
- software support math coprocessors such as some CAD, spreadsheet
- and graphics software. Not all software benefits from the use of
- a math coprocessor.
-
- The 80486 CPU combines the features of the 80386 chip plus the
- addition of a self-contained on-chip coprocessor and memory
- cache. Although the memory cache is small, a mere 8K, it is
- extremely effective since it is onboard with the CPU itself. The
- 80486 is useful for advanced scientific applications, CAD
- drafting, graphics and high speed LAN (local area network)
- shared computers in an office environment.
-
- An 80486SX CPU is also available which is essentially a "poor
- man's" 80486 with a smaller external data bus.
-
- Back to CPU clock speed. Older XT (8088 CPU) machines operate at
- a relatively slow speed of 4.7 to 10.0 Mhz or Megahertz. One
- Megahertz equals one million cycles of electricity per second.
-
- AT class machines (80286 CPU) operate in regions of 10 to 25 Mhz
- while 80386 and 80486 machines operate at speeds in the 20 to
- 40Mhz region. Obviously faster is better especially when it
- comes to colorful graphics displays, CAD drafting, large
- spreadsheets and massive programming tasks. However simple word
- processing, small business accounting and routine mailing list
- management is more than adequate at 4.7 Mhz. The need for speed
- is relative to the computing task at hand!
-
- Let's backtrack for a moment and discuss RAM memory. Most
- computers are sold with a specific amount of memory installed on
- the main "motherboard". Increments of 640K to 1Meg of memory are
- common. It is commonly advertised that additional memory may be
- added as "expandable on the motherboard" to some upper limit
- such as 4Meg or 8Meg. Thus the user can easily install plug in
- chips of SIMM's (single inline memory modules) to sockets on the
- motherboard. If possible, insist on SIMM memory modules which
- are simpler for the average user to install rather than earlier
- DRAM chips. Additional plug in memory boards can also be
- installed into computers having an 80286 or higher CPU. Up to 16
- Meg of RAM memory is possible on 80286 CPU equipped computers.
-
- Why install more memory beyond the 640K which DOS can address?
- For fast memory caching, RAM disks, TSR installations, access
- to programs which can use either or both expanded or extended
- memory, to run the Windows operating system or OS/2. These
- software requirements are not terribly exotic - but are simply
- ways to improve performance and speed for more experienced
- computer users.
-
- The hard disk is also a consideration in any computer purchase.
- CPU speed is determined by the clock speed of the computer while
- hard drive speed is determined by two factors: access speed and
- drive type.
-
- Extremely fast hard drives operate at 18 milliseconds access
- time or faster. Bargain computer hard drives operates in the
- range of 28 to 40 milliseconds. Hard drives must also be mated
- to a controller circuit which offers its own blend of
- performance and economy. MFM and RLL drive/controller
- combinations are earlier and less expensive hard drives while
- ESDI, IDE and SCSI drives are faster and more expensive high
- performance options. See the PC-Learn tutorial on hard drives.
-
- Floppy drives come is various configurations. Budget computers
- may contain only a 1.2MB floppy drive and hard drive. This
- configuration can read two floppy densities: 1.2MB and 360K
- floppies. A more flexible computer contains a hard drive, 1.2MB
- floppy and 1.44MB floppy. This computer can read four floppy
- formats: 1.2MB, 1.44MB, 720K and 360K. Ask if a budget computer
- can later be upgraded to include other drive configurations. The
- new smaller drives housing the rigid "mini floppies" such as
- the 1.44MB and 720K formats hold 20% to 50% more data in a
- sturdy plastic case with spring loaded dust door.
-
- For aspects about video configurations see the PC-Learn tutorial
- on video circuits. Briefly, monochrome is suitable for low end
- word processing but today's software usually requires VGA color
- resolution as a minimum. An affordable option is a VGA video
- card and a MONOCHROME (black and white) VGA monitor which
- provides an acceptable 64 shades of gray with most modern
- software applications.
-
- Several sources of computer equipment are available - each with
- a different flavor.
-
- 1) Manufacturer direct or direct sales, such as Dell, Northgate
- and Zeos. This method usually assures relatively high quality
- at fairly attractive price savings since you are dealing
- directly with those who design and manufacture the computer.
- Service is usually good, via telephone, FAX and BBS. The
- downside is that you must deal through the mail and await
- delivery. Price is very attractive, but not necessarily the
- lowest available.
-
- 2) Retail vendors such as Computerland or Tandy. Convenience is
- the factor here since service, returns and delivery is handled
- locally. You pay slightly higher for this additional
- convenience. Generally this is the most expensive computer
- purchase option.
-
- 3) Mail Order Houses. Almost 15 percent of PC sales are
- conducted by mail. Mail order houses do not completely design
- and build their own systems like direct sellers but rely on
- imported and pre-manufactured assemblies. Technical phone
- support can be variable, but if you shop carefully, you can save
- even more over local retail or manufacturer direct channels.
- Mail order sources are available in newsstand magazines such as
- Computer Shopper and PC Sources.
-
- 4) VAR's or Resellers. These specialized vendors usually provide
- systems in volume frequently with "value added" features such as
- special software setup, training or unique customization of
- computer systems.
-
- 5) Home brewers. The ready availability of computer components
- has spawned a cottage industry of small shops, some in home or
- low rent office spaces which can custom design a system or allow
- you to build your own computer using parts and facilities which
- they provide. These small, minimum overhead operations can
- provide extremely low prices but guarantees and service
- contracts should be provided in writing and background of the
- vendor should be investigated carefully.
-
- What are some questions and requirements in purchasing a system?
-
- What speeds are available on the CPU? 10 Mhz is standard on XT's
- with 12 to 20 Mhz on AT's and 33 mhz on 80386 machines. How many
- free slots are available on the internal motherboard for
- expansion with future upgrade circuits? Five to eight expansion
- slots is desirable except on small laptop computers. Is there
- both a serial and parallel port? How many of each? Mouse port?
- Is a clock chip included? How big is the hard drive? 40 to 80
- Meg is considered somewhat standard in size today for most hard
- drives although smaller 20 meg hard drives are useful for light
- office use computers.
-
- How many bays are available for extra drives? Two is minimum.
- How many floppies? What size of floppies? Most computers today
- minimally have either two floppies OR one floppy and one hard
- drive. Who makes the hard drive? Seagate, Connor and Miniscribe
- are considered reasonable, although not exclusive choices. Who
- makes the floppy drive? Teac, Panasonic, Sony and Toshiba are
- considered reputable in floppy manufacture.
-
- Whose BIOS chip powers the machine? Phoenix, Award and AMI Bios
- chips are all fine. How much memory is installed on the
- motherboard. 640K is a bare minimum for all machines with 80286
- and 80386 machines usually offered with at least two to four
- Megs of RAM memory. Any memory cache chips? Any coprocessor
- installed? Coprocessor socket available?
-
- What warranty covers the product and for how long? Does the
- warranty cover both parts and labor? Does the vendor have
- sufficient inventory to replace the entire computer if problems
- arise? Is there a different warranty for the printer? Who
- provides the service? What is the vendor's return policy AND
- refund policy. Is there a restocking charge? Is there a discount
- or change in price when dealing by check or charge card? How
- long has the vendor been in business? Is the warranty 90 days,
- one year or two years as some manufacturers are now offering?
- Money back guarantee? How long? 30, 60, 90 days? What type of
- refund on this guarantee: store credit, cash, exchange? Will you
- put it in writing? Shipping and handling fee? Visa card
- surcharge?
-
- How good is technical support? Is there a toll-free support
- line? 24 hours or limited hours? Is there a BBS (modem)
- telephone line for support?
-
- Is maintenance performed on site (the customer's location) or
- only at the vendor's location? Response time? Special
- conditions? Is the on-site service essentially the same in
- terms, such as parts and labor, as off-site?
-
- Has the vendor sold computers to buyers in your business
- specialty (medical, for example). References? How long has the
- vendor been in business?
-
- What is the estimated life of the PC? Of the hard drive? How far
- can it be upgraded? In RAM memory? How many expansion slots?
- Can the CPU be upgraded? The display and graphics card? What is
- the MTBF or mean time between failure of the components such as
- the hard drive and printer according to printed manufacturer's
- literature?
-
- Does the computer come with ALL the parts you will need such as
- monitor and graphics card? On many bare bones systems this is
- extra.
-
- Are the accessories from the same manufacturer? Is the item
- available for immediate shipment or is a backorder the option of
- the moment? When will it be shipped? Has there been a recent
- price increase?
-
- Any financing options available from the vendor which offer
- advantage over bank or credit card purchase? Leasing options?
- Bank financing carried by the vendor? What bank?
-
- Extras included with purchase? Documentation? DOS software? What
- version? DOS 5.0 is the latest. Mouse? Software installed on the
- hard drive? Is it legal software? Is is commercial software?
- Shareware?
-
- Any training classes provided? When? How often. Brush up
- training free?
-
- What utilities and extra software comes with the machine? Any
- hard drive menu systems or utility software? How is the
- documentation? Really good or just whatever the manufacturer had
- translated?
-
- What display monitor and card are included (if any)? VGA is
- standard. EGA is minimum. CGA and Hercules are the bare minimum.
- Are printer cables included with purchase of the printer? Any
- spare printer ink cartridges included?
-
- How is the keyboard. Springy and clicky with a tactile feel or
- just mushy and so so?
-
- Is the Basic programming language included or is this an extra
- cost. Will the manufacturer throw in a software package suitable
- for beginners such as Microsoft Works? Is the machine FCC class
- B certified (the best) or class A (acceptable)? What is the
- interleave on the hard drive (1:1 is fastest)? Is the keyboard
- an 84 key type or 101 key type?
-
- Is the computer case metal or plastic? How hard or easy is it to
- pop the cover and install new circuit cards? Does the keyboard
- plug into the front or back of the machine? The front plug
- option is a sometimes more handy. Is the reset and on/off switch
- on the front, back or side of the machine? Front is again more
- handy. Panel lights on the machine to indicate CPU speed and
- hard drive use? Keylock for security? How many copies of the
- key? Does your key fit all the computers in the store too?
-
- Does a local computer club/user group buy from the vendor which
- might provide personal references who can discuss why they
- bought from that vendor?
-
- For those who wish to read published reviews concerning specific
- brands of computers, printers, monitors, modems and software:
- the most complete resource is PC Magazine published by Ziff-
- Davis and available at most libraries and many newsstands. PC
- Magazine editors usually select one or two items within a
- product classification as their "Editors Choice." The complete
- index to both PC Magazine as well as their product review index
- is contained in their on-line modem service PC MagNet.
- Instructions for reaching PC Magnet by modem are contained in
- the Utilities section included within each issue of PC Magazine.
-
- For product reviews of hardware and software you may wish to
- download the PC MagNet files PCM.EXE, PCSRCH.EXE and PCM.INF
- which are quite large. The files occupy more than 2 Megabytes of
- disk space and require about 1.5 hours of somewhat expensive
- modem connect time. Alternatively, you can reach the same
- index of products on line within PC MagNet by typing GO REVIEWS
- which allows you to search the product review database directly.
- A larger database of 130 periodicals and their respective
- product reviews can be viewed by typing GO COMPLIB from within
- PC MagNet. Additional product review sources are suggested on
- page 27 of the June 26, 1990 issue of PC Magazine (Vol 9 No 12.)
- Page 397 of the same issue contains instructions on reaching and
- using PC MagNet by modem.
-
- If you do not have a modem or a friend with that capability, a
- low-tech method for reviewing specific computer hardware and
- software recommendations is to visit a local library which
- contains back issues of PC Magazine. Glance at the magazine
- cover for highlights of products reviewed in that issue. If you
- work your way from the current issue backwards in time for 6 to
- 12 months, you should find detailed reviews on the equipment you
- are investigating. Many computer clubs maintain a library of PC
- Magazine issues and may be a source if your local library does
- not subscribe to the magazine.
-
- Yet another way to constructively shop for computer equipment is
- to obtain free catalogs which are provided at no charge by
- reputable computer vendors and manufacturers. See the listing of
- free equipment catalogs contained in the recommended
- reading/bibliography section of PC-LEARN elsewhere on this disk.

-
- PURCHASING A LAPTOP COMPUTER
-
- ----------------------------------------------------------------
-
- There is an allure to purchasing a laptop computer. They are
- small, sleek and highly productive. What features should you
- consider when purchasing a laptop? For those who need quick
- highlights first we'll present a brief overview for the cautious
- laptop buyer. Later in this tutorial we'll shift gears for a
- broader "beginners" overview.
-
- Before jumping into our tutorial, a reading recommendation.
- Visit your local library and locate a back issue of the August
- 1992 edition of PC Magazine. That issue covered a variety of
- reviews concerning specific laptop machines and also contained
- some surprising suggestions for productive laptop use. While on
- the topic of pertinent reading, check for other useful titles in
- the reading list section elsewhere within this tutorial.
-
- Next, general suggestions for laptop buyers...
-
- 1) The keyboard is the most important interactive part
- of any laptop. Is it awkward? Could you use it for longer than
- 15 minutes? An hour? A complete morning at work? Note the
- location of frequently used keys like the backslash \, the F1
- function help key, the cursor control keys. Some oddball laptops
- require you to use a shift-funtion key combination for cursor
- keys. Not terribly comfortable. Othertimes the cursor position
- keys are oddly laid out in a non standard pattern which is
- difficult to use and memorize. One of the classic keyboard
- layouts is the Toshiba 286 T1200XE. Glance at the layout on this
- machine and compare it to your target laptop.
-
- 2) The screen. Next to the keyboard this is the greatest delight
- - or pain - when it comes to using a laptop computer. Can you
- use it for longer than an hour? Screens can be either backlit or
- edgelit. Each has advantages. Try both and see which you like. A
- few clever laptops have screen reversing software built in which
- can change the screen from black lettering on a light field to
- light lettering on a dark field. Helpful for some folks. Ask if
- your target machine has it. Find out if you like it. Is the
- output VGA (display and run most software) or lowly CGA (run
- and display fewer packages?) Is there a port on the back so you
- can plug in your big monitor to the back of the laptop when you
- are home or at the office? Do you need to buy an adapter for
- this? On an airplane tray can the screen be tilted so that the
- seat in front does not bump into the screen edge?
-
- 3) Weight. Fully outfitted with adapters, disks and batteries,
- what is the real "workday" weight of the laptop? Load the
- machine and accessories into a carrying case and heft it for a
- while. Brochures proclaim extremely light weight figures - in
- real life you will carry the computer and accessories.
-
- 4) Price. Determine the REAL price. You will need an AC
- adapater, carrying case and probably spare battery as a minimum.
- You will need DOS and some software. Beyond that, most people
- need a few manufacturer specific cables and sometimes a modem.
- Add it ALL up.
-
- 5) Battery life is a touchy subject - ultimately the attraction
- of laptops is the opportunity to get work done on the road.
- Battery life of an hour or so isn't much real work, when you
- think about it. Two to four hours on a fully charged battery is
- a working range today. Ask if the laptop has special battery
- saving features such as sleep mode, pause and resume, user
- selectable delays for drive and screen refresh use, powerdown
- mode, capability to change batteries without shutting down the
- machine and loosing data. Nice features. Is it easy and FAST to
- change batteries or a real chore? Look at the clasps and snaps
- as you open and close the battery compartment.
-
- 6) Modems. Someday you will need one. Does the laptop have a
- standard serial modem slot to which any low priced modem can
- be attached or a proprietary manufacturer specific slot to which
- ONLY that manufacturer's (expensive) modem will attach? For a
- few extra dollars consider a modem with combined internal fax
- send and receive capability which is a godsend for travellers.
- Much cheaper in the long run than paying your hotel $6 per page
- to transmit and receive faxes.
-
- 7) How much memory can you add to the laptop? For light word
- processing and spreadsheet work 640K may be all you need. But
- serious software use, Windows use or high end graphics may
- require 2 or more Megabytes of memory. How much can you install
- into the machine? How much will it cost? Can you install the
- additional memory or must the factory?
-
- 8) Drives. A standard 3.5 inch floppy drive is almost essential
- today. A hard drive, too, if you can afford it. If the laptop
- has no floppy, you might need to purchase special software and
- cables to transfer files between your laptop and desktop
- computer. One more expense. Back to the hard drive for a moment:
- if you work with large mailing lists, huge databases of clients
- or unusually large spreadsheets you MUST have a hard drive with
- larger than average capacity. Between 40MB to 100MB would be a
- wise investment for hard drive intensive storage applications.
-
- 9) Details. Beyond a serial port (for the modem or mouse) does
- it have a parallel port for a printer? How about capability for
- an external keyboard? Slot for math coprocessor? Null modem
- cable for transferring data between other computers.
-
- 10) Form follows function. If you plan to use the laptop mostly
- as your PRIMARY machine at home and work, focus on maximum power
- and expandable features. If you are a power user of Windows and
- graphics software you will need VGA display, at least 2MD of ram
- and at least a 386SX processor. However, if your primary work is
- spent on the road in planes and trains, pay attention to long
- battery life and quickly interchangeable battery packs.
-
- 11) Consider the new breed of tiny portable printers which work
- well with laptops. Included are the Diconix 150 Plus which
- weighs in at 3 pounds, Canon BJ-10 Bubblejet, Citizen PN48 and
- Star Micronics StarJet SJ-48. All printers will need spare ink
- cartridges, printer cable, paper, AC power supply and spare
- batteries.
-
- A brief glance at portable computer configurations....
-
- Laptops are for the most part single-piece computer systems
- weighing in at between 7 to 15 pounds. In most cases the viewing
- screen opens in a characteristic "clamshell" manner. All are IBM
- compatible and most will functions from AC or battery power.
- Most offer some expanability in memory and some, but not all
- will even accept an expansion board. The latest designs can
- mater to a "docking module" which adds powerful desktop features
- when the units are used in a stationary office setting. Prices
- range from about $700 to well over $5,000 for advanced models.
- Examples: the Toshiba T4400SX, Librex M386SL, Bondwell B-310SX,
- Dell 320LT.
-
- Notebooks weigh in at 4 to 7 pounds and usually feature both AC
- and battery power. Both hard drive and floppy drive models are
- available. Prices range from $700 to about $2,000. By far
- notebooks are the most popular category in the consumer
- marketplace and for most users have the best balance of weight,
- cost and features. Examples: Epson NB3, Dell NX-20, Tandy 1800
- HD, Sharp 6220, Tandy 110 HD, NEC 286F UltraLite, Compaq LTE286,
- Toshiba T1200XE.
-
- Palmtops. The smallest of the small. Weighing in at a pound or
- less these machines features minaturized keyboards, vestpocket
- size, lack of hard or floppy drives and varying amounts of true
- IBM compatability. Features are sacrificed in the quest for
- miniaturization. Some, such as the Hewlett-Packard 95LX contain
- built in software such as the standard Lotus 1-2-3 spreadsheet.
- At this writing, only the diminuitive Poqet palmtop is equipped
- to run most IBM compatable software. Tiny credit card sized
- memory modules are available for some models. Prices range from
- about $400 to over $2,000.

- 22 BASIC COMMANDMANTS OF COMPUTER CONSUMERISM
-
- ----------------------------------------------------------------
-
- 1) Does the computer contain sufficient RAM memory and CPU speed
- for the applications you intend to run and how easy is it to add
- more memory? A 80286 computer may be fine for word processing,
- for example, but a poor choice for extensive desktop publishing.
-
- 2) Is the computer FCC approved with an FCC sticker? Class A or
- B? Class B is better since it means certified for home use and
- theoretically emits less objectionable static radiation.
-
- 3) Have you identified the software you will (or might) be
- using? Can the machine run that software? Is DOS included with
- your machine?
-
- 4) As your needs change in time, will the machine expand or
- change with those needs?
-
- 5) Is the outer case of the computer large enough to accommodate
- additional expansion circuit boards? How many?
-
- 6) Is the power supply sufficiently large for future expansion?
- What is the wattage of the power supply? Is the fan noise low or
- NERVE WRACKING?
-
- 7) How many and what kind of floppy drives do you need?
-
- 8) Is the hard disk (if the machine contains one) certified for
- use with the internal controller board which operates it? What
- make on the controller card and hard drive?
-
- 9) Is the hard disk set with the correct interleave factor?
-
- 10) Will your dealer offer superior service after the sale? Who
- does the service? Where? Any free training classes?
-
- 11) Are all warranties in writing and how do they compare to
- other dealers warranties in writing?
-
- 12) What kind of monitor will you need and does the video
- adapter card inside the computer allow for monitor upgrades and
- will it display the software you intend to use?
-
- 13) Are you buying the computer or a sales pitch?
-
- 14) Are the internal components industry standard? Especially
- the floppy and hard drives. What brands?
-
- 15) Is the dealer trying to sell you more/less than you need?
-
- 16) Have you set a realistic budget?
-
- 17) Have you gathered information for all sources such as
- friends, magazine reviews, stores and advertisements? Are you
- relying on one computer guru from work or, more wisely, several?
-
- 18) If the price is far below the average, something is missing.
- What is it? Quality of the hard drive, lack of higher resolution
- video, toll free telephone support, software such as DOS?
-
- 19) Determine the REAL price by extracting hidden additional
- shipping charges, credit card surcharges, restocking charge if
- item returned.
-
- 20) Pay by credit card if possible since if you end in dispute,
- your credit card company can go to bat for you and issue a
- credit until the dispute is resolved. In addition, many credit
- cards automatically double the manufacturer's warranty.
-
- 21) Get details in writing. What is the salesperson's name? What
- is the exact shipping date? 24 hours? same day? Get it in
- writing via FAX. Retain the ORIGINAL AD which promoted the
- computer. A paper trail established early is the best
- protection. Retain warranty cards long enough to test all
- equipment functions first! If you mail in manufacturer's
- warranty cards too quickly, you may have to settle for
- warranty coverage rather than replacement by the vendor.
-
- 22) Retain all original cartons and packing material. Many
- vendors ABSOLUTELY require it in case of return!
-

-
- MUSCLE FOR COMPUTER CONSUMERS - THE LONG ARM OF THE LAW
-
- ----------------------------------------------------------------
-
- If you are dealing with a mail order supplier, Federal Trade
- Commission rules apply! Essentially the vendor must ship the
- order within 30 days of receiving it unless the advertisement
- states otherwise. If a delay will be experienced in shipment,
- the vendor must notify you in writing of a definite new shipment
- date and also offer you the chance to cancel the order with full
- refund. That notice must include a stamped or self-addressed
- envelope or card which allows you to indicate your choice. If
- you do not respond, the seller may rightfully assume you accept
- the delay. However, the vendor must either ship or cancel the
- original order within 30 days after the original shipping date
- which was promised.
-
- Any refunds for order cancellation must be made promptly. Even
- if you accept an indefinite delay, you have the right to cancel
- the original order at any time before the item is shipped. If
- you chose to cancel any order, which has been paid by check or
- money order, the vendor must mail a refund within seven business
- days excluding weekends and holidays.
-
- Likewise if the order was paid for by credit card, the vendor
- must credit your account within one business cycle following
- your cancellation request. Store credits and other methods or
- offers of similar merchandise are NOT acceptable unless you
- agree. If the original item is not available, a substitute item,
- even if similar, is not acceptable unless the vendor has your
- consent. Report violations to the Federal Trade Commission whose
- phone number is usually listed in the blue pages (government
- section) of your local telephone book. Tell the vendor you are
- reporting violations to the FTC and mail the vendor a copy of
- the letter you wrote to the FTC. This usually brings action
- quickly.
-
- One primary conduit for recourse is the Direct Marketing
- Association which maintains an action line for problem
- resolution. First you should attempt to deal directly with the
- seller, but if a problem is not promptly resolved you may wish
- to contact the Mail Order Action Line, c/o DMA, 6 East 43rd
- Street, NY, NY 10017.
-
- The first step in any attempt to seek redress from a vendor is
- to notify the supplier in writing that the item is defective
- and include a copy of the invoice with information as to model,
- price, date of order and account number if available. Retain a
- copy of your letter seeking refund or replacement. Any phone
- calls should be followed by a letter.
-
- Generally do not return the item to the vendor until told how
- and when to do so, since many have formal return policies and
- require "return authorization numbers" which are usually issued
- to you by phone or in writing. The return authorization number
- accompanies the defective item on its return. Keep a copy of the
- shipping receipt and packing slip. Any rights to recover postal
- or shipping costs is determined by the policy of that vendor as
- is usually stated in advertising and product literature.
-
- You may also consider contacting the attorney general for the
- state in which you live as well as the state in which the vendor
- does business. This can be MOST effective especially if you send
- a copy of that letter to the vendor. If the product was paid for
- with a credit card, you may also retain the right to withhold
- payment or cancel payment which is usually arranged directly
- with your bank or credit card issuing agency. This is explained
- under provisions of the Federal Fair Credit Billing Act.
