We have tried unsuccessfully to install IBM Token Ring cards - both the IBM Token Ring Network Adapter II (4Mbps, 16K RAM) and the IBM Token Ring Network 16/4 Adapter (16Mbps or 4Mbps, 8K to 64K RAM) - in Leading Edge Model D PC's, and each each case they fail the Diagnostics Diskette Initialization test. I've always assumed that Model D's were fairly representative XT clones. What other experiences have people had with these boards? Do they work with other XT clones? We've had no problems with AT's, Compaq 286's, 386's, etc. Geoff Arnold, Internet: garnold@sun.com Manager, PC-NFS Engineering UUCP: ....!sun!garnold PCDS Group, Sun Microsystems Inc.

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.
