Hi - I recently picked up a descent IIc and it booted fine but the keys didn't work. I checked to ensure the keyboard button was engaged and disengaged but still no keys work. However, control and reset does reboot the machine.
I have tore the machine apart to clean up the components and inspect them. I also took all the keys off and cleaned up the key connectors and also checked for continuity. All seems fine.
After reassembly I have the same issue. The keys simply won't work except the control and reset.
Does this seem like a bad keyboard chip on the logic board?
Thank you in advance.
