Re: [N8VEM-S100:6460] Re: CP/M running, But now what ?
Yeah, I could get the scope out, but not tonight...
The original linear power supply was damaged in shipping when
I bought it so I put in all new switchers. It has been running
stable with another board set for years.

Can you check how much ripple you are getting on the 8V supply?
I really can't think of what else to check. Your RAM is testing good now, right?
Is anyone else having this problem?

You can do this, and just watch the input from the other device. When you run DIR on the console I/O you should see the same output on both. Same goes for input from the terminal.
