I'll ask one of the designers when he gets back from his hols :-) Since I think it is a voltage regulator of some sort, I suspect the answer is no. The only dead board I ever knowingly found in the pile of cards that I inherited back in the lab at DEC was a DHV11 and it had had that very component knocked off. That's Al Kossow and he's certainly here (and there and evrywhere ...) http://www.decdocs.org points to the main ones. There are a few more that come and go, plus a scattering of sites with just one or two manuals. I don't know of anyone trying any serious OCR - the technology has leaped forward in recent years, but not to the point that it "just works". Given that there are somewhere between 300 and 700 DEC manuals online (just an estimate) any OCR process has to be more or less one button push (i.e. as effortless as straight scanning can be). If you can get Mentec to agree to having them made available (ask about bits of RSX and RT-11 V5 while you are at it ...) then let me know and I'll get the CDs online. I did ask but I've not heard anything back. Antonio
