Bad switches?

[bmlw]

Hello,
I have a mid 1980's HURCO BMC30. It was a case of the price is right. It always seemed to have button issues but eventualy you would get what you needed, primarily when starting up and needing to calibrate all axis. Now it seems to have gotten to the point that it wont work at all even though the screen fliks as though you have actualy done something. Am I correct in thinking this is a switch problem, and if so is there an easy fix or do I go looking for new switches?

Thanks in advance.

Could be a bad keyboard or CRT controller card. Check you don't have any keys stuck down with goo.

Thanks, as soon as I can I will take a look at them. Where is the best source if I need new ones?

You could try that fella Buddy at AMTS.
