Mike,
I just found you message about having the ciruit diagrams for a Disk Smith System 80. I
found one of these the other day in a recyling center and always had a soft spot for them
as it was first computer. The one I found works, but has a problem in the video circuit.
It is repairable, but would be a lot easier if I had schematics to work from (I collect
video games from the same era as well so my skills in repairing these would help me a
great deal :) If you have a scan or even a photocopy of this manual, I would glady
purchase it off you.
Cheers, Geoff
