That is the correct PROM. Mine is a 74287.........But how do I program the prom?..........Also, I don't need 25 of them.....maybe 3. Thanks for the info.......Now that I know where the PROM is in the CWID board and the part number maybe I can find someone to program it for me.

The original prom is probably a 74287 and they easy enough to find... still. There's a guy on Ebay selling tubes of them for just over $2 each, which is a great deal. LOTof 25 - MH74S287 - TESLA 74S287 - 74287 - ic -NEW Ebay Item number: 290104898405 I bought a few tubes from him and both he and they are the real deal. > If you know the PROM type one might be able to program and > replace.
