- The A1000 is the original amiga. Pizza box, and the keyboard fits
- underneath. A500 and A2000 are same basic computer, 'cept newer
- versions get more capabilities, of course the A2000 has a million
- expansion slots (or 1 more than I'll ever need, anyway). The A500
- just has the one on the left side (those for the A1000 are on the
- right side, so A1000 expansions cannot be made from the A500 stuff).
- All of these work with the motorola 68000, accelerators available,
- to the 68020 or the 68030 or the 68040 or now (for a mere $1599)
- the 68060. The A2500 is an accelerated A2000. All this stuff
- is 16-bit bus and the CHIP ram is clocked a 7MHz, the base speed
- of the 68000.
-
- The A3000 consists of 32-bit data paths and the Zorro-III bus
- (A2000 use Zorro-II). So a basic system speed 2x of the A2000,
- plus whatever clock speed. The A3000 also employs a scan doubler
- so that high resolution screens, displayed "interlaced" on the
- normal analog RGB monitor (TV-set frequency), is de-interlaced
- and bright at 60 Hz refresh, and plays on a standard VGA screen.
- The A3000 uses the 68030 at 25MHz
- or at 16 MHz but it can also accept accelerators.
-
- The A1200 and A4000 are basically the A500 and the A3000 adapted
- to use the AGA display chips, without the display enhancer
- found in the A3000 you need a multisync that syncs between
- 15 kHz and 31.5kHz such as the C=1950, C=1960, or AT1438,
- to get a variety of peculiar modes from the AGA display.
-
- If you're looking at used computers, the A3000 is routinely offered
- at bargain prices with plenty of memory (6MB).
