Also, an IPB (Inter-Processor Buffer) was made,
which connected it to a NORD-1, a not-quite-mini, not-quite-mainframe
machine. This has also, of course, been removed.
The CPU and IO planes, are, in short, FUBAR.
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.
There is 0% chance as is.
Well, then I say go to it. I think it's a bit presumptuous to say that it
would be impossible to re-wire a PDP-7, especially since someone or
something (was it done in an automated fashion at the factory?) had to do
it to begin with.
Difficult, yes, but certainly not impossible, especially if someone is
determined to do it.
Good luck! And keep us posted on your progress.
