Not just my schematics. As he says on that site, we exchanged quite a few 
e-mail messages about this. Essentially I talked him through the 
procedures, but I wanted him to understand what he was doing, so I 
explained what all the signals meant, what the various microcode 
addresses were, and so on. I hope he picked up a little bit about the 
workings of these fine machines.

While it's good to help get another classic working again, it's even 
better IMHO to pass on the techniques as well.
