catching up...
Most of what has already been said here is pretty
much correct. I'll add:
B-series were regular low-profile micros.
CBM-series had integrated monitors. I've never seen one of the
CBM series machines.
IMO they're pretty nice machine which had some attractive options
when they came out. They didn't last long and very little seems to
have been written for them.
You can find schematics for the B-128-80 in the archive (Web/FTP).
If any of you need a drive for one of these CBM 4040's work fine
(8050 is a better but less common drive). I have a number of
4040s and could definitely part with a couple if you want to pay
the shipping costs (heavy, heavy drives).
As soon as I clear through the research I have several items for
this series that will go in the archive - the manual, a word
processor and a spreadsheet, and some technical notes.
Any of you hard core commodore folks know who might have ended up
owning the rights to this stuff?
