The genaeology of the Amiga: A1000 - the classic A2000 - what happens when CBM Germany gets to play with design. this was sold in Europe and Canada for a while before the US design was ready. B2000 - the West Chester version of the A2000, known as the A2000. this is the only version ever sold to the general public in the US. A3000 - the latest. So... the '2000', in general terms, is the 'B' version, but is what you know as the A2000. If you haven't owned an 'A'2000, the German version, consider yourself fortunate. -larry -- It is not possible to both understand and appreciate Intel CPUs. -D.Wolfskill +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+

Pardon me for my ignorance but I saw a few postings about an Amiga B2000.
I always thought the Amiga line was A500,A2000,A3000. Is the B2000 a
different version of the 2000? Someone please clarify this for me.
Thanks

A2000 is the original, German-developed 2000. B2000 is the American remake,
which is easily recognized by it's 3 RCA jacks instead of two (composite B/W
video). It's main advantage is that it's upgradable (uses the chipset with
Agnus, Paula, Denise...). A500's and B2000's do, A1000's and A2000's don't.
I have a question there, myself: Is it possible to upgrade a B2000 to
2 MB chipmem as in A3000? Any problems with other chip upgrades?
- Thanks

The first 2000 to be sold was the West German designed version which was essential a A1000 with slots. Same Angus as the 1000 and 512k on the motherboard with another 512k on a board in the coprocessor slot. This version was apparently not sold in the USA. (lucky for you people!!) The motherboard was version 4. When the American designed 2000 was made (It was a better design) it was called in the afore mentioned countries B2000 to distinguish it from the original 2000 which was called the A2000. Pioneers like myself who jumped in a bought the first 2000s ended up with a 2000 that turned out not to be the normal 2000. After much moaning at Commodore about orphan machines I managed to resolve the problem at some cost. There are still a few of these machines in use but they suffer from subtle hardware difference from the B2000s that make some software and hardware not work on them. I only wish Commodore knew how the sales of the A2000s hurt their credibility among loyal Amiga people. My B2000 is going great however and I am still pleased I bought an AMIGA!!!!!

Is the B2000 a >different version of the 2000? Someone please clarify this for me. There are two major versions of the A2000. The original, the A2000-a, was a 4-layer board based on the original A1000 motherboard logic (eg, thin Agnus and all those buffers). This machine had 512K on the motherboard. Not long after this machine was introduced (Europe and Canada, it was never sold in the USA) it was replaced by the A2000-b, or "B2000" as it's sometimes called, is a 2-layer board design which is based on the A500 motherboard logic (eg, Fat Agnus and Gary) along with its own custom bus control chip. This machine has 1 megabyte of memory on-board, and both the video and coprocessor slots are supersets of the original A2000-a slots. It also has the A500-style monochrome composite video output. The easiest way to tell the difference, externally, is to look at the back of the machine. The machine revision is given by the formula: 'A'+ (char)(number_of_RCA_jacks-2) Chances are extremely good that any arbitrary A2000 is of the "B" variety. That's just about certain in the USA (the "A" version wouldn't pass the FCC certification necessary to sell a computer in the USA). >Pete Babic - pab@po.cwru.edu | I'm not totally useless - -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy Get that coffee outta my face, put a Margarita in its place!

OK, Netland gurus, I'm one of those poor unfortunate souls who bought an early A2000. This machine has performed almost faultlessly for me since it was first bought, and I have no intention of replacing it yet. MAYBE?? You see, it all depends upon the answer to my current problem/woes... namely, I want a hard disk in the thing. Now are there any problems sticking such a convenient device into one of these models, and if not what is the cheapest/ best/safest combination. What about things like WB2.0, AV, etc., etc.... Will these great new convenience goodies be pliable enough to work inside my machine?? The answers to these questions will determine the outcome of a long and fruitful/meaningful relationship with my machine. Will keep you all posted...
