Series 80 keyboard cleaning

[Paul Berger (Canada)]

If you have keys that are sticking one common cause is the square tube that the key top fits into splits at the corner and they spread a bit and bind. I have not found any reliable way to repair them once they have cracked, I have yet to find a glue that will bond to them. The keyboard technology used was pretty common so it is not impossible to find a donor keyboard for replacement parts. One source is the early black TI-99 at least some used the same technology, the white ones do not.
