A black screen with a little jumble of "snow" where some text should
be. My guess was that the lines are not interlaced correctly?

Maybe I wasn't very clear in my first message...
When connected to an Amdeck (is that how it's spelled?
I'm at work now so I can't see it) monochrome composite
monitor I get a clear legible display with a few
"artifacts" when some colors are displayed. There are
one or two switches on the back of the monitor which
I had to fiddle with to get a good display.

That would be hard, as the boards are pretty tightly packed into
the box. They are not really available when the machine is in an
operational state.
