OK, I think we need some clarification here. What does your "B-128" look
like? My B series user guide indicates four distinct models...

1. C128-40 "Advanced Personal Computer"
Basically this is a B128-80 with a 40 column screen (sounds like a VIC
chip to me) and comes in a low profile case (sorta like an amiga or 64)
Not to be confused with the more common C128.

2. and 3. B128-80 "Advanced Business Computer"
the manula says there were two versions of a B128. A low-profile model
and, of course, a high profile one. The low-profile model is like the
C128-40 but the high profile model has integral disk drive(s) and display
and a detachable keyboard. The low-profile, of course, required external
drives (IEEE-488) and video.

4. B256-80 "Advanced 16-bit Proffessional Computer"

this model only came in the high profile case (I think) and came standard
with 256k ram (as opposed to the 128k i the other "B" computers), dual
processors (6509 and 8088), and "spots" for optional Z80 and 8087 co
processors. Really neato looking machine.

Well, I'm "in" to Commodore and don't yet have one so if yer willing to
sell/trade, lemme know!

Also, if you want a copy of my "User's guide" that shouldn't be much of a
problem, it's a whole 120 pages.
