What if anything is it compatible for right now? I have one that came with a 1984 IBM PC AT computer and was wondering what, if anything I can use it for. I also have the computer it came with originally, a fairly good shape AT, but I don't know if I should keep the keyboard, sell the computer or keep them both together. I am ultimately still looking for an IBM 5150 PC, and I know the keyboard is probably not compatible with that. That's why I'm asking.
