While you're here, how about checking out the Astronomy Book List ?

You are right that they may have some errors and that some information
is incomplete. Generating such schematics is a horrible problem. I
never pursued perfection because it is all but impossible to reproduce
the circuit. There are several chips, such as the programmable gate
array and the proms that have proprietary code.

However, that said, I will send you a complete set of dead electronics
is you will contact me privately. I too would like to see a complete
and absolutely correct set of diagrams. We may even be able to decode
the gate array. :-)
