It would have been nice if you guys had helped me out with this when I recently posted that my "K" key had inexplicably quit. I swapped the keycap out with the ESC key because that is rarely used; I didn't think of the extra shift key. Long story short, I overestimated my abilities and thought I had wrecked my unit permanently, but by hook or by crook, and solder bridges and resistor legs, my keyboard was fixed. Except for the escape key. Actually the cassette relay and the modem don't work, but I think that is from changing those resistors and replacing the backup battery. Don't see how it could be the keyboard.
