I've got a CBM 8032 that powers up "fine", but the screen is filled with
"!" on
every other character position. When some letters are repeated, they can change,
i.e. "nnnn" becomes "onon" which seems like (without checking the
ASCII charts)
that the "n" and "!" are ORed to become the "o". Anyone have
any ideas what the
problem might be? Most of the schematics I have are buried someplace, so I
thought I would start here.
