Thanks for that set of data. There used to be a wealth of datasheets for
both boards and chips, but that went away. Here is at least some of that
data, which I appreciate.

If people have more of that, it would be nice if we could collect that
and upload on a suitable place.

I also appreciate Art's postings, and would enjoy getting updates on that.

My Z3801A has a failed PSU I think, so that needs to be resurrected. I
have a few others that I would wish would get operational.

Cheers,
Magnus
