I got it to work, but I was very lucky. The key that was stuck was F10;
top row on the open end of the plastic layers. I slid a piece of
cardstock in between the contacts and no more stuck key.
So the DEC Pro gets through the diagnostics, boots, and enters the VAX
console program... Now if it was only connected to an actual VAX.
I have been
working on a DEC Pro 380 and the LK201 keyboard I have
causes the Pro to report a stuck key and hang. So I opened up the
keyboard thinking I could clean out whatever had jammed in there.
The clear plastic part is in 3 layers. The top layer has conductive
traces on the bottom surface. Then there's an insulating sheet with a
hole under each key (and no traces). And the bottom layer has traces on
the top surface. There are circular pads on the ends of the traces under
each key, over the holes in the insulator.
