Well some of it runs now! But I think getting it all running will be fun... Things I think should work don't, and things I think shouldn't work do. So the PSU and Reference Voltage Generator work fine, but the Reset/Hold/Run switch was totally gunged up. I had to prize it apart and clean the gunge out. I know its switching relays but there is a snubber network on the back to prevent the bigger spikes.. I was a bit worried about the Meter but it seems to work reasonably well.
What I am missing are some resistor plugs to go on the inputs of the amplifiers but I think I will replace some of the blank panels with resistor panels. Sadly no time to play tonight, got to finish a talk for some students tomorrow....
