Hi, after a visit to the local tip this week, I have a few Data General books available (no computer though :-(). Data General Interface Designer's Manual for Nova and Eclipse line computers and the following EMI books detailing the system and programming of the DG machine coupled to a medical scanner: Scintron 3 camera diagnostic softwares Scintron 3 service manual Scinticamera detector head NE8900 & NE8960 IO tester for eclips processor Parts A & B Nova 3 Exerciser test (N3EXS) Eclipse microcode flowchart Eclipse basic instruction ROMS and Decoding Nova 3 Multi-Programming Rel (SH) (N3MORT03) a number of these seem to be re-bindings of the equivalent DG publication. They cost me a beer for the lot, yours for the cost of postage (and a beer if your feeling generous :-)) Jim. (weight is around 6lbs for the lot) Please see our website the " Vintage Communication Pages" at WWW.G1JBG.CO.UK
