I have seen ads in PC magazines for Cyrix and IIT coprocessors, quite a bit cheaper than intel ones. I was wondering are they REALLY 100% compatible with IBM (clone) machines, and whether you can just plug them into the existing slot like an intel coprocessor and have them behave exactly as an intel coprocessor (except faster I believe, according to the ads)?? I would appreciate any advice, Thanks, Lynne Bilston Dept Bioengineering, University of Pennsylvania bilston@eniac.seas.upenn.edu
