The SwTPC computers were all based on the SS-50 bus
and Motorola microprocessors.
There were three basic models, the original
"6800" system, followed by the
"6809", and later by the
I admit to some confusion over model numbers, as I have run across far
more model numbers than variations in machines.
I think that one variation on the S/09 was called the 69/A or 69/K
("A" for "Assembled" and "K" for "Kit");
another (perhaps with hardware memory protection?) was called the S+/ .
A variety of peripherals and software was available, both from SwTPC and
from third parties.
SwTPC also manufactured video terminals. The earliest predates even the
6800, and was called a "television typewriter". At some point, this
seems to have become their CT-64 terminal. With 16 lines of 64 characters
each, it was small by today's standards. Later on they introduced their
CT-82 terminal, which had the more usual 24 by 80 screen, and a very
elaborate set of control sequences.
