on a scale of 1 to WE COPYRIGHTED THE FUCKING PLASTIC CASE OF OUR DUMB TERMINAL, how many layers of IP law are you on?
it's a well known fact that injection-molding piracy was rampant back in the Reagan era
dang it. I did a decent job cleaning up this part of the case but I accidentally put it down the wrong way and damaged a clip. I'm gonna have to shim & glue it to have it attach properly
This is going to take forever to clean. I basically can only clean one channel at once with a cotten bud, and even that is tricky
significantly cleaner! qtips, paper towels + spudger, and toothbrushing it got basically all of it.
they didn't remove the little peely plastic protective film! This thing is from 1986! that's 38 years of PEELING LEFT UNDONE!
They clearly used this machine in the famous lucasfilm Dust Factory

So I resoldered the couple of questionable caps and put it partially back together, but it's still got the RAM issues. I was kinda hoping the caps would alleviate that problem.

I still can't get into the testing mode since I don't have a keyboard for this specific unit, so I can't figure out which memory chip it is that's failed (and there's like 5 on the PCB)

@foone If you have replacement RAMs, you can piggyback them.

Take the known-good chip, bend the legs in a bit, and slide it on top of the suspect part so the good one's pins make contact with the suspect one. If your problem goes away (or, sometimes, changes in a meaningful way), that's probably the bad one.

It's a low-grade technique, but you can't argue with results.
