Does anyone out there in netland know of the whereabouts of any derelict Systron-Donner SD-80 analog computers? OK, quit laughing for a moment and listen! We have one that we still use for small physiological systems models and it's just lost its +100v supply, which is constructed of a wonderful collection of obsolete components. We'd like to get a junker, even a fragmentary one, to use as an organ donor. Or, does anyone have a drawer of Westinghouse 154-18 power transistors that they'd like to clean out? Evidently ordering a new one causes Westinghouse to go out and start mining the silicon upon receipt of order. There don't seem to be any equivalents. Any leads on either whole or fractional computers or transistors will be received with effusive expressions of gratitude. Suggestions to use a digital simulation will be less enthusiastically greeted (actually, we're bringing one up, but still want to maintain the analog).

#R:medman:-102400:trsvax:55000005:000:312 trsvax!ron Sep 6 10:00:00 1984 Wouldn't it be a little easier just to scrap the 100 volt supply and build a new one from scratch?? Anyone familiar with basic electronics could do it, in fact, if you searched your staff and found someone that was a ham radio operator, he/she could easily build a new one. 100 volt supplies are easy to make.
