Does anyone know where I can get some documentation for a Xerox 820-I microcomputer? Is there a user's group for these things? Steve Ferry ukma!steve@anl-mcs.arpa

The CP/M interfaces with the monitor EPROMs for I/O, and these monitors are similar to the old APPLE MONITOR or ZAPPLE MONITOR. Xerox has an outfit that handles the distribution of these manuals, but I'm sorry to say I discarded the 800-telno and name after acquiring my copy of the document. The check was made out to "XEROX Inventory." I suggest you call or write: Xerox Corporation 1341 West Mockingbird Lane Dallas, Texas 75247 which is the address given on the back page of the "Software Development Guide." Good luck, Ed Baldwin, Burlington, N.C. ihnp4!burl!egb
