I seem to recall reading something in the past about there being a separate crystal and that therefore the 8038_ family was the first where you could mix and match different speeds. Does anyone know the technical details or have tried this and either failed or succeeded? (The reason I wish to know is that as a student on a tight budget, I would be willing to buy a 80386-16 rather than a 80386-33 even though I would be taking a hit on FLOPS if I can get a substantially better price.) -- Above text where applicable is (c) Copyleft 1991, all rights deserved by: UNIX:/etc/ping instantiated (Ping Huang) [INTERNET: pshuang@athena.mit.edu]
