Hi,

Of course Paul D is the expert here. I had an idea that I wanted
to throw out:

If the reset threshold is not set correctly, could the supply dip enough when the CPU
gets busy responding to some button push to cause reset to glitch on?
Maybe not long enough to reset the CPU but long enough to mess it up?
Does that make any sense?

Bob

Hi Paul,

It stalled after pushing a bank button.
Besides switching it on did stall most of the time as well.
Guess some part
in the power circuit is acting up.

After having opened the unit and pushed on some ICs and
hooked it up to the
power again it blew a fuse.
So I guess I have to get it looked at by a professional.
(Which I'm clearly
not)
Hopefully he can fix my mistake.
