Fact: the PC tech ref says the part is 8k x 8 in size. Recollection: I think you can make an exact duplicate using a 2764. However, there are two address pins switched, so you can't easily burn a modified version. I remember seeing an adaptor used to allow burning a new ROM with a standard PROM burner. -- bill davidsen (wedu@ge-crd.arpa) {uunet | philabs | seismo}!steinmetz!crdos1!davidsen "Stupidity, like virtue, is its own reward" -me
