I asked a while back about the different 80287-compatible chips on the market, and I received several useful replies. Basically, I learned that at a given clock speed, the IIT 2c87 is faster than the Intel part, and the Intel chip is faster than the AMD 287. Now there have been a couple new twists: the price of the 2c87 has dropped, and there appears to be more than one AMD 287 on the market. The 2c87-20 is now down to $165, and the 287XL is $185. This makes the choice a virtual no-brainer. Also, as the 2c87-10 is $127, is there any reason anyone would go with the significantly-slower $100 AMD chip? And finally, a couple of companies are advertising AMD 80C287-10s and 80C287-12s at different prices ($110, $130). AMD advertising does not mention clock speeds. Are these really the same chip, or are there multiple AMD 287s? Also, what is the highest workable clock speed for the AMD 287?
