I thought I was nearing completion of my restoration of COMPUTER, the name I have given to my Apple ][+ clone made by MCA of Japan... that is, if the silk screen on the motherboard can be trusted. And I'm going for a restoration here, with exceptions made for adding a Super Serial card and any expansion cards needed to make the ones that were included work.
Last week, after confirming that my other clone board works, we tried to swap chips between COMPUTER and the working clone board. After not having luck with any of the expected chips, and even less than expected chips, I managed to notice that I had a 74S195 installed in COMPUTER where the working clone board had a 74LS195... and when I swapped those two chips, the fault on COMPUTER changed. Better yet, that swap seemed to fix the mysterious zero page errors in Dead Test.
This begs the question: did I install the wrong type of chip anywhere else on COMPUTER?
Will we find the bad logic chip? Will I find more bad 4164's along the way? Will that Disk ][ Controller Card start working in COMPUTER? You'll have to watch to find out!

A viewer sent me a goodie box, containing parts that need work. The end goal: an Apple ][+. Lets see whats inside, and what work lies ahead. Well also probably look at COMPUTER, as I know I need to order parts for it as well.
What parts are in the box? How bad could it be? And how many of COMPUTERs chips are now testing bad tonight? Youll have to watch to find out!
