New: Z-100 schematics, scanned by Richard Pestinger.  Barry Watzman provided the following note along with the schematics:

"Also worth noting, there were two different Z-100 motherboards, the early (or the so-called "2653") motherboard and the later (or the sol-called "2802") motherboard. All of the documents and schematics are of the earlier one. I don't know if printed documentation of the later one even exists."
