Here is the summery that we distribute to users that ask. The machines that we have experience with that WORK with IBM Token Ring Type PC/XT/AT Tested By Comments Compaq 386 AT-Clone GSIA NCR PC8 AT-clone GSIA Compaq Deskpro 286 AT-Clone GSIA Epson Equity II XT-Clone GSIA Leading Edge Model D XT-Clone GSIA Clock interrupt was in conflict disable clock or set alternate TRN interrupt. Mirage XT-Clone Data Set to Inter. Level 3, the PC seemed to function fine. ARC (model 10 Turbo) XT-Clone Data When working with clones with a faster clock speed, keep in mind that each IBM TR card is ARC (model X Turbo) XT-clone Data different. Try a few cards until one works. AT&T XT-Clone Data P.C. Design GV286 AT-clone Data Works at 6mHz, but not at 12mHz. Maxum 286 Turbo AT-clone Data Works at 6mHz, but not in Turbo mode. Sperry IT AT-clone Data Works at 6 and 8mHz, but not at 7.1mHz. Clone P.C.'s that DO NOT WORK with IBM Token Ring Type PC/XT/AT Tested By Comments Kaypro PC10 XT-Clone GSIA Panasonic Executive XT-Clone GSIA Even using a expansion box that Partner Portable allows IBM cards, we have not been able to get it to work.
