Hi again all

Tony asks:

When I unplug the keyboard and short out what I think is
Enter (OK, maybe it's something else) the screen still
refreshes, no lights on the floppy drives.

>leaky (about 100k between the pins when the key is not pressed). This

At least 3 of the switches seem to be dead shorts. And it's an
assemble-once keyboard, the keys have little plastic pins that
are melted to keep the whole affair together.
