  1. Thanks, I appreciate your follow-up here. Also, sorry for junking up your thread. I really like the device and the only problems I've had with it are my (or my cat's) fault.
  2. So... I suspected something like that should be the case, but when I checked various points with a meter, I found full continuity between these points: - USB +5v line on the STM32 (on what was left of the trace after that connector was ripped off) - pin labeled "5v" on the STM32 - pin 2 of the SD Card connector on the ST/E hard disk PCB - "vcc" on the SD card reader I get that maybe some of those are supposed to be 3.3v and by supplying 5v I'm potentially risking damage... But then why did those points all show full continuity with the 5v input line?
  3. I cut open and soldered a USB inline power switch to +5V and Ground where the SD card PCB connects, and now it's working again (if a bit janky looking).
  4. One of my adorable cats yanked the USB cable off of my unit and the carnage is in the attached image. Assuming I only need ground and 5V going into the STM32, is this salvageable? I think so (I'll try something to get it going again) but always welcome opinions from others...
  5. After 20 years these probably aren't available, but hey, let us know if it works out.
  6. I'll keep posting random stuff whenever, kind of a half-assed blog. Next: Before and after "sunbriting" my IIgs for a full day (rotating things to follow the sun). It wasn't badly yellowed to start, but it was very noticeable particularly on the left side of the main unit and monitor. The results are not 100% but it lightened up pretty evenly and looks OK now.
  7. Thanks! It's important to me to be able to see them on display (yay dopamine hits) but also that they are working and usable. I think they'd look better on a long white built-in desk-thingy with good lighting, shelving, etc. but I haven't wanted to commit to furniture beyond the folding tables so far--unfortunately they are starting to sag...
  8. I collected 80s computers in the early 90s, then sold almost all of them because emulators, and then decided I missed real hardware so I started again. I restarted the collection in 2010 with just a couple of computers that were impactful in my life (PCjr, Apple IIe) and it just exploded from there. Even looking for good deals, it's hard to pay $$$ for things that were basically e-waste in the 90s, but when I look at what I've spent over the last 12 years, it's still a pretty cheap hobby. It is fun playing with the modern devices people have created; that was the game-changer for me. For now, I think I'm done adding new platforms and slowing down on new gadgets for them.

  9. There was also "The Visible Computer" by Software Masters but it appears they only released it for Apple 2, C64, and a separate 8088 version for IBM PC.
  10. The 65XE package here is a killer deal and if I didn't already have something similar, I'd buy it! Also, I did a recent transaction with Tuxon86 that went well. Free bump.
  11. Looking for a working VIC-20 BASIC ROM 901486-01 for around $15 shipped (in USA). Let me know!
  12. Following up to myself: read several related threads. Inspired by the thread below, I suspected the crystal X101. I reflowed the solder to it and I got color back! Then it went away after I reassembled the entire unit. Took it back apart again, hit it again with the iron, tested, reassembled. Color out of sync on first boot, but it worked every power cycle after that. So either the part is marginal or I did a bad job twice of reflowing the solder. If I upgrade the video I'll replace the crystal at the same time (I assume they're available). Otherwise I'm going to leave it assembled. Afraid of breaking more things (the plastic cartridge guide already lost a clip...).
