Has anyone traced the pcbs for the H724 pdp-8/e control cards? One of my power supplies has failed and the only schematics I can find are in maintenance manual 1 with no component values or layouts. I can trace the circuits myself I guess but I’m just looking to save some work. (The 5v and power OK control card layout is a bit of a tangle!)
 
Thanks for that, never looked there :oops:
I've got copies of most of the bitsavers pdp8 stuff on my workshop computer of course, just never thought to look at that one, thanks for the heads up.

Some differences there from the maintenance manual 1 (Sept '73) and the machine I'm repairing (also '73) but minor.
