it's not a repeat...
I recently read an article in the EE Times about the AMD 80C287, and it went
into some detail about the fact that AMD has the genuine Intel microcode
through a contract they signed in 1976. Intel is currently battling to prove
the 80287 code is not included, but in the meantime we have a $99 80C287
available that SHOULD be 100% compatible. I have dealt with AMD in the past
and they seem very responsive to customers, so the purchase is not of shady
equipment from an obscure company, but a reputable chip maker. Further, the
target market (says AMD) for this chip is the "rest of us" who cannot afford
Intel's scalping. They intend to sell tons of these, so I would speculate that
much testing has been done to ensure it is correct.
I have had direct experience with AMD as an OEM, buying and using tons of
EPROMs and microcontrollers, so I can vouch for their validity and quality.
The only precaution I would take is buying from a reputable distributor, so as
return would be easier if there were something awry.
Further, the speeds are supposed to range up to the fastest '286 AT bus... I
have no definate on this so please ask the seller - or AMD.
BTW, this litigation between Intel and AMD would mean 386 microcode availablity
to AMD if they win... (486 is not included, tho).
