--------------Original Message: From: Marvin Johnston <marvin at rain.org> Subject: CBM 8032 Garbage on Screen 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. --------------------- My guess would be a stuck bit D0 in UC4 (even chars) or UC6 (odd chars), a 2114, notorious for its failure rate. mike
