Here at Carnegie-Mellon University, we have an installed base of almost
900 IBM Tokenring Adapters (4 meg type) and we have tested a number of
clones.  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

Leading Edge Model D    XT-Clone       GSIA   Clock interrupt was in conflict
                                              disable clock or set alternate

                                              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.
