How much are you willing to spend? I can check for you but I am always asked for this. |

Guys,
what is the difference between these chips:
80C287 (eg. AMD x80C287-10)
80287 (Intel C80287-10)
2C87 (IIT 2C87-10)
they are all math coprocessors. Are they cross replaceable? Pin to pin? pls advise
According to the pinout of 80287 and 80C287 the last one has pins 1, 2, 3, 37, 38 and 40 that are n/c comparing to 80287. Does it mean 80287 could replace 89C287? |
