Nice! I have the Service Source CD to 8/93, no schematics, board level only, nice take apart, troubleshooting and parts lists. I've never seen the hard copy version of the computer service manuals. I also have the Peripheral Interface Guide 1/91 spiral bound booklet that includes Apple II, III, and Lisa stuff as well as the newer Vintage Macs. It's a treasure for the switch settings and cable connection pinouts!
