You've gotta pound it and you might get 2 "2"s for your trouble. I assume that the keyboard switch is made of unobtanium (If you know of a substitute chime in) so I'm thinking of swapping it for the "COPY" key which I guess is useless unless you have the built-in thermal printer. 1. Do you simply pull the keyboard button off the switch or is there a trick involved? 2. Any other gotcha's? Thanks, Marc My guess is that the VT52, VT55, VT05 and LA30 are identical. The key fits snug on a plastic white pin, shaped as a ?+?. Over the plastic pin is a small spring. If the spring is not installed, the pin will simply ?fall down? due to gravity, causing a continuous ?key pressed? signal. You can (gently) pull the key cap. If the pin does not ?fall down?, you have the reason why it is hard to use: dirt or dust. Henk, PA8PDP
