Non clicky HP41 key

[TASP]

I have managed to clean under the LCD without a desolder, but it had to be rough on the hardware. I managed to get some lens wipe material that was saturated with TV screen cleaner. I wrapped it around a flexible paring knife blade, and I can't recommend anyone else try that. I was able to clean mine, I did not sever a finger, but surely somebody has a better way of doing it.

I had the LCD pulled quite a ways out of alignment to do this, it couldn't have been good for any of the hardware.

(machine was not in very good shape from battery leakage, so I was willing to get tough on grime with it, there was considerable poo on the glass but I got it all off)
