[vcf-midatlantic] Visual 50 terminal troubleshooting

[William Sudbrink]

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.

  Thanks,

Bill Sudbrink
