There are essentially the same computer, and always called "A2000" when you
got to buy one.  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.
