I have a 386SX40 motherboard that keeps spitting out a Keyboard Error at POST no matter what I do - I checked all continuity from the keyboard port to the KBC and elsewhere and they are all intact, so I have come to terms with the fact that I will need to desolder the 80C42 KBC and replace it with a socket..
The only spare KBC I have at hand right now is a 83C42 which, according to its datasheet, appears to be pin compatible with the 80C42. Am I safe to just plug that in to the socket when done?
