I have a feeling it's like the link says, 4L video RAM bad.
Absolutly, I bought a bunch of "untested" ones off ebay a while back and fixed them all. Out of about a dozen, only one was working.
So did you just shotgun the SBCs and replace all 7400 chips? Could I piggy-back the chips and then just remove one at a time in an attempt to narrow it down to a single bad chip? Or in your experience is it usually more than one bad chip?
