Micro Cornucopia sells three varieties of Kaypro schematics, for $20 each, with a theory-of-operation keyed to schematic. - Kaypro II & 4 (pre-84) - Kaypro 10 (without modem) - Kaypro 2, 4, 10 (84 series) Schematics are on a single 24" by 36" sheet. They include serial and parallel port details and programming examples, and other nitty-gritty details that is hard to find elsewhere (e.g., how the Kaypro II bios switches between video and main ram banks). I have both the Micro-C schematic for Kaypro II, and a bootleg copy of the dealer's manual and schematic. The Micro-C version is a lot better than what Kaypro provides dealers. Address: Micro Cornucopia P.O. Box 223 Bend, Oregon 97709 Phone: (503) 382-5060 (9am to 5pm, PST) They take Visa and Mastercard, and prices include postage. I've ordered from them by phone, and got good fast service. They also have a technical help hot-line, the number of which I don't want to broadcast to the net, but you'll find out about it if you decide to buy a schematic from them. I've called the technical hotline and gotten good help on tracking down a hardware problem. In summary, this organization is a good resource to people with Kaypros (also Big Board homebrew systems, and Xerox 820 series.) I have no connection with Micro C, other than as a satisfied subscriber and customer. --Michal Young University of California, Irvine young@ics.uci.edu
