Circuit Diagrams


I am starting to collect together as many circuit diagrams relating to the Nascom and Gemini systems as possible. This is very much a personal collection, so please don't ask me to produce copies unless you are *really* stuck. It's not that I mind, but I just don't have the facilities to produce copies in any quantity.

I only have manuals for items marked "M".

Of course, if you feel the need to contribute something...
