DG Nova repair etc.

Hi all, Tony, thanks for your input, we will check the PSU on Thursday when we get to the machine again. as Christian pointed out, the problem is not so much the pure amount of components but the puzzle game of identifying them since they have been relabled. Whats definitely worse when comparing to out old VT100 is that the DEC manual has one complete definitive service manual that covers all schemes and logic. For our NOVA i failed to find a comparable thing. I have constantly to go back an forward through all kinds of docs. Again I may be unable to find a "real" service manual, if you know any let me know ;) Bruce, I am looking forward hearing from you. It would be great if you come up with anything helpful before Thursday so we can check everything out. Dwight, we are currently missing the exact schematics for our machine. I hope thats where Bruce comes into play. The only real schematics i found were for the NOVA 2, and a quick glimpse showed that the machine is different (at least the layout of parts). None the less we will keep our eye on the clock(s), i guess it will do no harm and make our scopes and logic analyzers happy ;)
