Subject: 486 heat: Worry about it???

    I recently upgraded to a 486 and discovered that since my hard
drive is mounted vertically right above the cpu, the outter case of the
drive becomes a good deal hotter (not SUPER hot, though) than if the
drive is not above the CPU.  The best guess I can make just by feeling
the temp. change is probably about 20-25 degrees F.  Should I be
concerned about this extra heat with the drive above the CPU or not??
Should I mount the drive in an open bay instead??

A transaction generally takes a minimum of 3 cycles on an ISA bus.  If
the motherboard and card both support the zero-wait-state signal, this
can be reduced to two.  On the other hand, cards can assert an
arbitrary number of wait-states (within reason); ten or more is not
unheard of for some slower video cards.

So the ISA bus can run at up to 8MB/s and still be within spec,
although 5.33MB/sec is a more realistic assumption for an upper bound.

Subject: Character set translation

Dear Marshall,

Concerning your Q in IBMPCL92.189 I suggest you to look at the package
TSFLTB14.ZIP, which may be in the <MSDOS.TXTUTL> directory on SIMTEL20.
With that package (as far as I've seen from the DOC) it is possible to
replace every specifyable character(s) by any other(s), so you should
be able to define some kind of a translation table if you know the
translation between the character sets.

Regards - Jim.

Subject: digitizing a photograph

HELP! HELP! HELP!

I am at my wits end trying to figure out the easiest way to digitize a
photograph.

I have an application that needs the capability to take a still
photograph and bring it into an application.

I do not know any other method besides using a regular camera and
scanning in the photograph.  The problem with this is I am not sure
what kind of quality I would get from a color scanner and a photograph.
Also, the time it would take to develop a photograph is another
problem.

Can anyone recommend a good solution to this application?

Subject: HELP! My 486 is slower than 386!

I got myself a motherboard of 486/33 from our local computerstore.  The
rest of the system I put them together by myself .

And I just bought a Norton Desktop for Windows, in there, there is a
CPU speed test, from that I notice that my computer is slower than a
Compaq 386 with a index of 25 vs. 35.

Could this be the problem of CPU ? But I did not encounter any problems
when I am running this computer.

Or just a wrong crystal, but the one on the motherboard says it is a
33Mhz.

Any response will be appreciated. Thanks!

If your system is "rated" slower than a 386 system, there's something
definitely wrong.  MHz for MHz, the 486 should outrun the 386 by
roughly a factor of two.

Things to watch for:  make sure that the BIOS setting for your 486
system is set correctly.  _USE_ all the cache (internal and external),
_ignore_ the turbo (speed select) input  -or-  make sure the turbo
switch is in the correct place, and make sure the "default" speed is
high.

You might need to play around with the system memory/AT BUS timing
(clock divider and waitstates) as well.

Read the manual/call the vendor to get the most tweak out of your
system.

Good luck

When they spec how manys "layers" a PC board is made of, they are
talking about the signal traces on the boards.  You've seen PC boards
that have the circuit signal traces running both on the top and
botom...this would be a two layer board.  ie two copper layers
seperated by PC board material.  A four layer board is simply four
layers of copper that signals can be run on.

I find it hard to believe that todays motherboards are only four
layers.  At Motorola we design with at least 6 layers.  4 signal layers
with a power and ground layer.  In fact, the higher density boards are
being done with 12 layers.  8 signal layers and 4 power layers.  I
would be interested to know if they are only talking signal layers or
if the 4 layers includes the power and gnd layers.  If you don't
"shield" the higher speed clock lines and busses between power and
ground the PC board will be very "noisy" when operating and spray radio
wave interference all over the place.

Anyway... They are talking about the number of copper layers within the
PC board.

Mylex and Micronics are two well know and respected motherboard
manufactures.  Some of the other things to look for are the BIOS, the
chip set and the cache.  Phoenix, AMI and Award are the top BIOS
producers, know for good quality and compatibility.  C&T, OPTi and SSI
are popular chip set makers, thought there are scores of others.  Also,
look at the amount and type of cache on the motherboard.  It will
usually be in the 64k-256k range.

There are also dozens of asian motherboards being sold.  Most use
quality chip sets and BIOS chips so that they should be considered if
you're on a budget.  Now days most of the computer support circuitry is
contained in the chip set, so the motherboard is mostly just a set of
buses with expansion slots and i/o connectors.

My 386/40 board is a no-name asian clone.  It works fine with DOS,
Windows and SCO Unix.  I have also used DOS and Unix compilers and
debuggers with this motherboard and have never had a problem.

At work we have purchased a few 486/33 Mylex motherboards to upgrade
some old IBM AT's, they work well also.

Ask around at GE.  I bet some of your co-workers have already taken the
motherboard upgrade path.  They could give you valuable first hand
knowledge about upgrading.  BTW, it is extremly easy to install a new
motherboard if your computer case accepts standard AT or baby AT size
motherboards.  Most replacement motherboards are the baby AT size.  You
should check your case before you order.  If you have a funky case you
can order a new case with power supply and all mounting hardware for
about $60-$100, tower configurations are about $30 more.  --

Subject: Problem with WIndows 3.1

Thanks to all people who replied to my posting some time ago concerning
my problems with Windows 3.1. Most people advised to add more RAM, what
I did.  However, this didn't solve the problem.

The configuration of my system is:

  Processor     80386SX 20MHz
  Coprocessor   80387
  Memory        4 MB RAM
  Graphics      Trident TVGA9000
  BIOS          American Megatrend SCATsx rev 3.0 BIOS, 04/29/1991
  BUS           ISA (PC/AT)
  Ports         2 serial, 1 parallel
  OS            MS DOS 5.0
  Hard disk     (type 47) Quantum 50MB 8 sides, 750 tracks, 17 sectors/track
  Controller    IDE
  Mouse         Genius mouse, driver version 9.04, on COM1

PROBLEM:
  * When starting Windows 3.1 in (default) 386 enhanced mode, a
sequence of beeps is generated. The beeps seem to occur mainly when the
hard disk is accessed. The amount of beeps increases when adding screen
saver, desktop bitmaps, clock, and other add-ons. Starting a program
also causes beeps.

  * When continuing to run W3.1 in 386enh mode, sometimes strange
things happen. When scrolling in Notepad, numbers are inserted in the
file sometimes when pressing Up/Dn/PgUp/PgDn. Double-clicking a program
icon sometimes starts a program but then immediately iconizes it.
Pressing ALT-F4 or File... Exit in the program manager does sometimes
NOT close Windows.  When starting a large program, Win3.1 freezes and I
have to reboot the system.  * The debug switches of Windows do not
help.

  * DrWatson finds no fault.

  * I am using the Windows SVGA driver with svgamode=106 set. Changing
this or using Trident drivers (recent version from
ftp.cica.indiana.edu) didn't help.

  * I already experimented with various AUTOEXEC.BAT and CONFIG.SYS
changes, but that didn't help either.

Subject: R4400 > R4000 > P5 > 486 (Indigo kicks butt : -)

The recent issue of Computer Design has a little blurb in it about the
new R4400 chip from MIPS (now part of SGI). It's an upgrade of the
R4000 and basically runs faster and has a larger primary cache. The
current R4000 runs at 50 Mhz externally, 100 Mhz internally. The R4400
has a 75 Mhz external clock. Cache has been increased from 8k/8k to
16k/16k.

Anyway, the interesting thing for this group is that the article made a
comment about even the existing R4000 being faster than the
not-released P5 from Intel, not to mention the R4400. The R4000 has
been shipping for almost a year.

Here's a data point: I took somebody else's existing Fortran code to do
numerical chaos on a PC and recompiled it on my Indigo R4K without any
changes except for replacing the graphics calls (the program is
99.99999 % floating point, including much double precision). What took
an hour on a Gateway 486DX2-66 took four minutes on the Indigo. And
this was using a compiler that only generates R3000 binaries (i.e., no
64-bit instructions).

Regarding the flame wars: I own a Mac, Amiga, and 486 and have cursed
them all :-)

Subject: STACKER and New drive Installation

Dear Steve,

Concerning your Q in IBMPCL92.189 I would like to ask you whether you
do not put the hard drives into the finally desired systems and then
transfer the whole contents of the "old" drive onto the "new" one
serially. There are nice utilities to transfer files or directories (or
even whole disks) via a 0-modem cable. The one I use is the package
ZIP151.ZIP, that transfers at a speed of 115200 bps, but only files or
directories. So I wrote (in BATch) a set of utilities (which I will
upload to SIMTEL20 in due time) that uses ZIP 1.51 (and another utility
DISK), to transfer a whole disk or a part of it (a specific directory
branch). If you are interested in that utility (called CLONE) drop me a
line. I'm regularly improving it.

Regards - Jim.

Subject: Tape drive questions
Keywords: tape drives

I have had a CMS 250MB drive for about 4 months now. It was a MAJOR
life saver when I was installing OS/2 and I had to re-partition my hard
drive.  Just load the program, tell it to backup drive C, and go do
something else for about 1/2 hour. IMHO I think that once the drive
finds where it needs to be on the tape, the writing of the files to the
tape is faster then a floppy, even when working through a floppy
controller.

If anyone out there has a large library of diskettes with archived
programs and stuff you don't use very often, a CMS QIC-80 drive is a
great investment. Well worth the money! Not only will it eliminate that
cumbersome floppy library, it also makes backing up your hard drive
fast and easy. Also, I did some figures. Megabyte per megabyte,
cartrige tapes are cheaper then floppies.

There are still a few things about the QIC-80 that still bug me.

    1. You can't delete a saved volume unless you delete the entire
tape.

    2. This may be asking too much but I wonder why you couldn't
load and execute files off of a tape the same manner as you would a
floppy.

I talked to a CMS tech guy and he said they have been getting requests
for the ability to delete volumes off of a tape. Aparently he said that
this is strictly a software limitation. I guess they just need a large
enough demand and they'll get a team to start working on it.

Will the IBM ever be able to multitak like a big machine.?  I mean.  A

9 I/O processorsAnd the intel machines have ONE processor.  I try to
multitask and access a disk floppy drive and my machine crawls to a

pasing the process off to an alternate processor.  So, will the PC ever
be able to multitask as well as an Amiga? Or other non-intel machine??
It doesn't seem too probable to me, but then again maybe its the
operating system.  Does UNIX make the PC multitask much better than
windows, desqview, or OS/2??

Subject: Will PC's ever multitask well? Is it even possible?

Coherent 4.0 is a multitasking, multiuser, protected mode, 32-bit
operating system that resembles SVr3 unix.

I run Coherent 4.0 on my 386dx/40 with 8MB of RAM.  I can format both
floppies at the same time, and have two make/cc/as/ld sessions as well
as several interactive users logged in at the same time, and all my
cron jobs (jobs executed periodically by the CPU).

PC's multitask very well.  The floppy controller can operate in
parallel with the CPU; so can the hard drive controller, etc.  If you
want fast video for a PC you can get a card with an additional
processor.

The problem is DOS programs; they busy-wait whenever they are waiting
for I/O, keystrokes, disks to spin up to 3600rpm etc.  Under Coherent
(and all unixes), process can wait on events.  When a process is
waiting, the CPU switches to another process.  When the event occurs,
the CPU puts the waiting process back into the list of runnable
processes.  Thus editors wait on the keyboard, a copy to floppy will
wait on disk spin up, download programs will wait on the com port.
Only programs that do large amounts of number crunching are ever
interrupted due to priority (because they have had too much CPU time).

I think you know not of what you speak,  I'm running SCO Open Desktop
on 3 PC's on my machine.  I have 3 IO subprocessors in the compaq, 2 in
the Zenith, and none in the Daly.  This all has to do with what kind of
hardware you put in your PC.  Multitasking has nothing to do with your
floppy being slow.  It has to do with you not having a separate
processor memory bus.  When you access any peripheral in your bus you
processor must slow to the bus speed (8MHz for [E]ISA, and 10 MHz for
MCA).

Multitasking is an OS feature which the intel fully supports.
