Hi Storm08.  Congratulations on the Lisa!

That is really early.  I actually received one today AppleNet# 00100302 mfg date 83076 and I thought that was early :)

Anyway, does the mouse work?  They are both controlled by the same 40 pin 6522a VIA chip on the I/O board at D7.  The Lisa actually has two of those chips.  The other at D5 controls the parallel port so you may want to try to swap those and see if that helps.

I'm not sure your finger is enough to simulate a keypress.  If you have an ESD bag (the kind that chips or boards come in), they are mylar and the same material the keypads use.  You can try to make a little circle and try that on your finger tip.

Good luck and keep us posted.
