Discouraging start to the day...

Well, I don't know what the heck happened here, but my keyboard decided not to function today. It was working fine last night... I burned a new BASIC EPROM chip, plugged in the firmware card, powered up the board, and now the keyboard is not working. Some keys work: 1, A, S, D, E, H, J, K, L, Q and that's about it. Most of the other keys do not work. My keyboard has always been flaky, and restarting usually worked. But today, no deal!

UPDATE: I hooked the keyboard up to an Apple II Plus and verified that the problem is the keyboard.

So...
