faulty hp-20s keyboard


hello all,

i have a problem with my hp-20s, the last column of keys didnt respond to keypress... when i applied pressure on the upper righthand corner of the keyboard (just above the sigma key), the keys works again, what should i do?



Use it until it dies, and buy a backup.

Easily obtained for $20 to $40.




I think it can be fixed but required some tricky surgery, look under fixes for the 32/17 etc.

Try looking at: http://www.hpmuseum.org/guest/brogpion.htm

The text there doesn't look encouraging so may be best to buy another and experiment with the broken one.
