After I got my Glitchworks RTC/CMOS power module, and soldered it to the chip, I started having "201-Memory Error"s pop up (unrelated to the CMOS chip), and the system seemed to hang (with a blank black screen, no orange display) on cold restarts. I figured they were legitimate at first, as indeed one of the connectors was not pushed in all the way. (The board that connects the memory expansion and modem to the motherboard)
I kept getting them, so I cleaned the offending connector with Deoxit. Still no change. So I took out the memory expansion. It cleared the bit pattern indicators (to show what bit was not working), but I still kept getting errors, and at least once, the diagnostics picked up a "System Board Failure" error, so I used Deoxit on the base memory and slots. However, I kept getting the error even afterwards, but then it started bootlooping, with a different hexadecimal number every time after the bit indicators. (i.e. BD00, 4676, 8000) I probably should have seen this coming, because I had a similar error (Disk Controller Failure) when I refurbished the system back in 2018. It mysteriously cleared itself when I started it up a few days ago to test, since the
Everything seems ok, but after faffing about with that, I have come to the conclusion that the capacitors in the power supply have finally fallen out of spec. (Even though a lot of people might say replacing the capacitors is either a fluke or stereotypical snake oil at best.)
EDIT: Checking them this morning, I found that the capacitors have seemingly fallen out of spec. (a 470uf cap read in the 500uf range, and a 1700uf cap read in the 2200uf range!)
I'll be getting new caps from Mouser.
