In the early 80's, the "micro" computer had become both a hobbiest machine
and a learning tool. It was also becomming an affordable tool for small businesses.
Commodore Business Machines charged into this new market with upgraded versions of
thier popular "PET" line, called the CBM 8000 series. Although these machines
are advanced "PET" computers, the reasoning for labeling them "CBM" instead of
"PET" may have had more to do with the business marketing plan than the
problems that plagued the CBM 3001 series.The 8000 series is characterized by their 80 column screens, which were a first for the PET series, and their "business" (non graphic) style keyboards. They also show Commodore engineers introducing "external" memory to break the 32k architectural barier.
Although these computers are named different, they are in most ways
identical to the older PET computers. They include the
advanced BASIC 4.0 environment, IEEE peripheral support, and powerful 6502
processor. Be sure to check out the PET 2001 entry for more
general information on Commodore PET computers.
Unfortunately, many of the great games and programs that have been written and designed for the PET 40 column screens no longer work on these new 80 column models. To releave this, programs were written to force an 8000 series PET to emulate a 40 column screen (by enlarging the right and left margins).
Commodore intially produced and made available 64k upgrade boards that would
give the 8032 an impressive 96k of total memory. Later, Commodore produced a new
model of computer, the CBM 8096, which contained the 64k expansion already installed.
However, very little software was written to take advantage of this extra ram.
ROM: 20 Kilobytes
Ports: MOS 6520 PIA, MOS 6522 VIA
Keyboard: Full 73 key QWERTY
Personal Note:
The 8032 is interesting, as it does not have the typical black
tape color across the front. Instead, there is a little plaque
proclaiming it to be the "CBM 8032". Also, quite inexplicably,
it plainly has a graphic keyboard.
The 8032s both came from local collectors, and the
8096 came from an eBay
auction.
