- PRODUCT NAME
-
- Commodore Amiga 1200 computer
-
-
- BRIEF DESCRIPTION
-
- The A1200 an excellent addition to the AGA Amiga line. It provides
- acceptable performance in a compact, inexpensive package while offering a
- generous amount of expandability for a computer of its size and price.
-
-
- AUTHOR/COMPANY INFORMATION
-
- Name: Commodore Business Machines
- Address: 1200 Wilson Drive
- West Chester, PA 19380
- USA
-
- (Non-USA readers should contact the branch of
- Commodore in their country.)
-
- Telephone: (215) 431-9100
-
-
- LIST PRICE
-
- $599.00 (US dollars)
-
- The total cost of the system reviewed was $1620 (US) including sales
- tax. This was under the "PowerUp" price and includes DeluxePaint IV AGA and
- FinalCopy 1.3 AGA. This software will be shipped to me in 6 to 8 weeks
- after C= receives my warranty registration card.
-
-
- MACHINE USED FOR TESTING
-
- A1200 with 2 MB Chip RAM and no Fast RAM
- 85MB Maxtor 2.5" IDE drive
- A1960 Monitor
- AmigaDOS 3.0
-
-
- GENERAL FEATURES
-
- The primary advantages of the A1200 is its use of the AGA chipset
- and a mostly 32-bit architecture. A note of interest is that this machine is
- based on the Motorola 68EC020, meaning it has a 24 bit address space just
- like the 68000 based machines, so the maximum RAM you can install will be 9
- MB. For a machine of this size, that should be more than enough RAM. All
- other aspects of the machine are 32-bit, including the AGA custom chips and
- the data bus. A 32-bit trapdoor expansion and a PCMCIA slot are standard in
- addition to the usual Amiga ports and a 2.5" IDE drive bay/controller.
-
-
- EXPANSION
-
- The A1200 comes equipped with a PCMCIA slot. This is a 16-bit
- expansion slot that has become popular in laptop machines. It offers some
- interesting potential for expansion; but because it is a 16-bit device, it is
- not well suited for general memory expansion. It does offer exciting
- potential for such things as modems, network adapters, SCSI/CD-ROM, and
- assorted PC emulators. With the release of AmigaDOS 3.1 and device
- independent network support it would follow that already available Ethernet
- adapters could be easily made to work with this Amiga. [MODERATOR'S NOTE:
- AmigaDOS 3.1 is not released yet, so any statements about it are not
- guaranteed at this point. - Dan]
-
- Underneath the A1200, you will find the 32-bit CPU trapdoor expansion
- slot. This was the primary reason I even considered the purchase of this
- A1200. This slot offers the potential to add 32-bit FAST ram, CPU
- accelerator cards (without violating your warranty!), SCSI controllers, and a
- whole host of really nifty stuff. I would like to see a Zorro-III bus
- expansion box that allows you to put your A1200 in a "pizza box" case
- connected via the 32-bit expander, giving you some slots and an external
- keyboard. Currently, there is a memory board available for the A1200 that
- accepts up to 8MB of 32-bit ram and has a math co-processor.
-
- On the back of the A1200, you will find all of the standard Amiga
- ports as well as a really clean Composite video and RF modulator output. I
- wish the mouse and game controller ports were on the right side, though.
-
- Internally, there is room for a 2.5" IDE hard drive. I installed a
- 85 MB drive here. Performance tests indicated a throughput of about 500KB/s
- on this disk. I suspect with the addition of FAST RAM, this will improve,
- since the disk buffers will be moved to FAST RAM. The floppy drive is the
- old 880K unit. Apparently the new high-density drives physically were too
- big.
-
-
- LIKES, DISLIKES, LIMITATIONS
-
- Memory Expansion:
-
- One must be aware of some memory expansion constraints.
- Although you can put up to 8MB in the 32-bit trap door slot,
- this will drop to 4MB if you insert a card into the PCMCIA
- slot. It seems these two slots share some address space.
- This is a minor nuisance.
-
- AGA custom chips:
-
- These new chips are really nifty! The displays they produce
- are clean and generally fast with the exception of 256-color
- hi-res displays. Again, Fast RAM should help some here since
- the CPU will not have to fight the AGA chips for memory
- access, thus speeding up the whole machine. Even so, the
- 256-color modes are DOG SLOW and are inferior to some of the
- PC displays I use at work. Compared to the ECS chips the
- new AGA chips really scream. I'm now running a 16-color
- Workbench, something I would never have done on my A3000.
-
- While I enjoy the new video bandwidth and improved
- color/spatial resolution, I must say I have one really big
- complaint: getting AGA displays centered on the screen. It
- took me a few days to figure this out. It is not in the
- manuals. I would like C= to provide a more transparent way
- of getting a MAX-overscan DBLNTSC screen centered on the
- display.
-
- AmigaDOS 3.0:
-
- Many of the additions seem to be hidden from the general
- user. The addition of CrossDOS is useful. The scroll bars
- are now 3D. The file requestor is not dog slow any more. You
- can put a picture on your desktop. Intuition now has
- intelligent palette sharing/allocation. And according to the
- folks at C=, there are now API calls for double-buffering
- animation.
-
- Memory:
-
- For users like me, the 2MB memory that the machine ships with
- is not sufficient for my usual Amiga use. I'm constantly
- running out of memory. It should be fine for the typical
- gamer/letter writer though.
-
- Performance:
-
- My previous Amiga was an A3000, and the A1200 cannot compete
- with it in sheer processing/disk speed. Benchmarks rate the
- A1200 with no FAST ram at about 25% the speed of an A3000.
- However, the A1200 crushes the ECS A3000 when it comes to
- video speed. If you want a low-end video titling genlock box,
- then the A1200 is the way to go. The A1200 begs for 32-bit
- Fast RAM, or better yet, an accelerator in the trap door.
- This machine with an 030 or 040 and Fast RAM would be
- awesome! If you are a person trapped in the land of infidel
- PC users (like I am) but still want a low cost Amiga hacking
- solution with up to date graphics and modest expansion
- potential, then the A1200 is the machine for you.
-
- Overall, I really like the A1200 and do not regret the purchase at
- all. I will add FAST ram as soon as I can, and plan on adding an
- accelerator later. If the cost of an A4000 makes you ill, then look into a
- A1200 system.
