RE: HP97 The journey begins
Well, after more analysis... I measured the transistors on all the quad transistor arrays, and they all seemed happy. So, I looked further upstream, and noticed that the trace from the ROM for segment F is bad. In fact, it looks like it has a fried transistor
Well, I guess that's "good" news in that a new CPU board from Teenix will solve this problem |
