I have a Visual 50 terminal that I am now troubleshooting. I got it in the late 1980s and it worked fine until 1995. I can't find a good schematic for it or ROM images. Its symptom is that it powers up to continual beep (solid tone, not repeated beeps) with a cursor on the screen. This is not in the troubleshooting table of the manual that I have.
I know the keyboard is capacitive foam pads. I was hoping that was the trouble, but it is not. I disassembled the keyboard and removed the old pads, replacing a few with some spares I had from SOL20 repairs. Has anyone corrected this problem before? I suspect that the EPROMs are going.
