Well there you go! :-)
I have complete documentation of the wires, and of
module locations,
they are all documented clearly in F-77 Maintenance Manual (which
you have on your site). They are easy to read, and give a complete
schematic of both the backplane, and the module locations.
If you have the wirewrap schedule, then you have a decent chance.
Maybe consider some sort of treatment for the posts? Deoxide?
(My old Varian came with one for some reason. It could be wired as a
16-bit or 18-bit machine by changing some dozen or 100 wires. The cards
were 6-bit slices of DTL and early TTL.)
