The technical manual is hosted on Terry Stewart's great System 80 site at: http://www.webweavers.co.nz/system-80/manuals_technical.htm The site has the manual with the copyright owners permission which includes the schematics.

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
