DEC RPR02 on eBay

I'll keep the stuff anyway. Perhaps there is some interest to put that to Al? Regards, Philipp http://www.hachti.de ------------------------------ The RP03 is an ISS drive and there will be little commonality in its schematics with that of the RP02/RPR02. For example, the former servos on a glass scale while the latter detents on a rack. As I recall the 660-1 (RP02) was a relatively short run product since DEC switched to the RP03. The Memorex 3660 (the IBM compatible version) was a much longer lived product so it got the benefit of many design improvements that were never in the 660-1. When Memorex refurbished a 3660 into a 660-1(refurb) I bet it got the benefit of all those improvements so it is likely the schematics are similar but different in detail. There is a 660-1 Maintenance Manual at bitsavers, no schematics. But the maintenance manual has a list of all the signals in the back panel so if you have the schematics that should be very helpful. Signals may have been added or deleted but the signal names rarely changed as the design was improved. You ought to consider posting those RPR02 schematics at bitsavers. Tom
