We (Perf. Tech.) recently completed a project that involved using 4 68020's running at 25 Mhz, 0 wait states. We used very fast static ram (each 020 has a 64K fast buffer, all 4 'share' a slower 8K buffer and all 4 have access to a 32 bit VMEbus and 64 bit VSBbus. The first time I ran the EDN benchmarks (against an older 16 Mhz 68020 design) I had to re-check the code/timings! john grana ..!rochester!cci632!walden!jjg
