In the not too distant past, someone asked what was the difference between the A2000 and the B2000. I must have missed the answer if anyone had replied, but I am curious. Are they even "related"?

There is no Gary and no New Agnus inside 512k of mem and a little card with 512 other k plugged in the cpu bus. If u use these card and want to use the a2090 in the same time, it's impossible. There is an arbitration problem with the cpu slot... Commodore say: you can exchange the main board for 300$ !!! (The price of a new board is also 300$) What do u say Commodore USA about this ? Milan

The difference is in the motherboard. What's called "A2000" in Amiga circles is the original 4-layer motherboard; "B2000" the newer 2-layer motherboard. If you bought it in the USA, or recently anywhere else, it's the 2-layer board. There are only a few differences. The "B" has 1 meg of RAM on the motherboard; the "A" has 512K on the motherboard, 512K on a daughterboard that sits in the CPU slot. The "B" allows a Coprocessor card to coexist with the 68000; the "A" requires that the 68000 be removed (along with the 512K daughterboard) to use a Coprocessor card. The "B" provides a monochrome composite video output, the "A" doesn't. The "B" provides a full-size video slot which allows the use of things like the MicroWay flickerFixer, the "A" has only a half video slot which supports GenLocks but doesn't provide all the digital video information. The "B" uses the Fat Agnus chip and can use the new 1 meg Fat Agnus, the "A" can't. That's about it. -- Dave Haynie "The 32 Bit Guy" Commodore-Amiga "The Crew That Never Rests" {ihnp4|uunet|rutgers}!cbmvax!daveh PLINK: D-DAVE H BIX: hazy "I can't relax, 'cause I'm a Boinger!"

(The price >of a new board is also 300$) Three hundred bucks, huh? Is this my chance for a cheap upgrade for my A1000? What comes on the B2000 motherboard anyway? Is there enough so that I can just add a power-supply, case, drives and a new keyboard? It might be worth it just to have a low-cost machine so that I can do hardware development without worrying too much if I blow it up. -------- Darren Leigh dleigh@hplabs.hp.com (Internet) hplabs!dleigh (UUCP)

You can easily build an adpater to use the 1000 keyboard and you really don't need a case (opps... your not from the FCC are you :-). If your serious about going this route (and im not saying its good or bad) I would suggest that you also buy a 2000 power supply. It might save you some head aches later. >-------- >Darren Leigh -- Dan "Sneakers" Schein {ihnp4|allegra|burdvax|rutgers}!cbmvax!heimat!sneakers Sneakers Computing 2455 McKinley Ave West Lawn PA 19609 Call: BERKS AMIGA BBS 24 Hrs - 3/12/2400 Baud Disclaimer: Any opinions expressed are 40 Meg -=- 215/678-7691 those of Sneakers Computing Of course heimat is an Amiga, doesn't everyone run UUCP & UseNet on an Amiga?
