Microsoft Diagnostics didn’t see any RAM issues and visually passed the graphics tests. Of course, buggy CheckIt flagged all sorts of memory. Didn’t feel it was ROM issue as the random characters were all valid extended ASCII.
With my magnifier glasses, started straightening a bunch of badly folded pins that extended to other traces. THEN I SAW A SMALL DEEP SCRATCH!
OMG, I was suddenly filled with real hope! Added four bodge wires and wow, it works great. Such a relief as I didn’t want to sink more money into this.Everything in this lovable hobby is getting so expensive.
Ah! Nice job!
Following the paths of scratches has lead me to repair a lot of cards in recent years. At this point most of these things have had decades to get crushed and scraped by much larger and heavier objects in some spare parts bin.
