I found that, if I type a long (but not too much) line and I want to delete
it, by keeping the INST DEL key pressed, after some characters the cursor
starts to move randomly on the screen and, sometimes, for having the plus/4
working fine again is necessary a reset.
I thought it was something wrong with my prototype, so I re-checked cable
connections. But they are ok. I think it is a bug of Ruud's design since,
with an original 7501 CPU, the problem doesn't exists.

P.S. Ruud, if you want to see it, I can send you the prototype board.
