IBM XT 5160 Keyboard issues

I was happy to find a IBM XT for a good price at the scrapyard today in very nice condition. It is missing the hard drive, but i have plenty of those, the controller was still inside. I had a little issue getting video working at first, i do not have a 9 pin cga monitor laying around, thankfully i found a 16 bit isa card that also works in an 8 bit slot. The machine starts up and runs its memory test, however it gives a 301 error. System halts and says press f1 to continue, but no luck, keyboard is unresponsive. I have tried about 10 different keyboards on the machine, including some model M keyboards with a ps2 adapter with no luck. A quick search does turn up that 301 is a keyboard related error, but i am not sure what exactly the issue is. Am i doing something stupid here or am i looking at the possibility of something being wrong with the machine? --Devin
