"Joe R." <rigdonj(a)cfl.rr.com> asked:
Any idea how much is involved in the electronics. Is
it all standard parts
or what? I foresee a run on Atari printers!
I don't understand the question. What is it you want to know about the
electronics? The PR-40 was sold as a kit so it would be very easy to work
on. I don't have a schematic, but I think it was mostly TTL with a
character generator ROM. The Atari 820 had more LSI chips, as usual with
Atari, and tin boxes around everything for TV interference protection.
