  1. Video recording of the process form start to finish
  2. They were a community machine shop in SJ/RWC, looks like they closed a couple years ago. You could have had one bent into shape from sheet metal there for you, the design is simple enough... @slomacuser Very cool!
  3. @olePigeon Glad I could help! Unfortunately this lot is still in Germany But the stand seems easy enough to make if you have access to any decent workshop. Mabe ask someone over at the TechShop if they still exist?
  4. @LaPorta No, just put droplets on the affected areas and let is sit until it evaporates, then add more to wet it and gently scrub with a toothbrush. Final rinse with IPA
  5. Someone mentioned vinegar, I like to use oxalic acid. It removes and sometimes reversed oxidation. Breaks up caustic battery electrolyte wonderfully
  6. How would that work, how would you control the polarization angle? It must be 90┬░ from the rear film
  7. Here's my gallery of a PB150 I did about a year ago https://imgur.com/gallery/xlJQgIW
  8. IIRC it wasn't too hard to add one, tapping into the trackball, because ADB is a parallel topology
  9. Oh man. When I got to the part where you said you saw the maxwell bomb I thought "impossible! The base SEs don't have those and the wired batteries I've never seen leak" then I saw someone has clipped the original battery out, installed a socket, and put a dirty bomb inside It may be salvageable. Do the acid soak as mentioned
  10. Yes, the stand has a sticker on it by Raduis - the other big player in Mac graphics. But nothing more identifying than that like a model Bonus underside shot showing reinforcements made in corners and under the top
  11. Just did an acid soak and preliminary scrub with soapy water. The ASIC looks fine. The Zilog is missing 1 pin which I think I can fix and the 2 onboard RAM are shot. Also lots of missing traces. Those I can handle, but I worry for the vias that go to inside layers. I'll have to get the schematic
  12. Here is the damage. It's bad but not terrible - I'm going to give it a shot. Luckily I have the other IIf to reference for parts and surface traces
  13. That corrosion isn't all that bad, use vinegar to neutralize it then scrub and rinse with toothbrush+IPA As to the PSU, check the low voltage side's caps for leakage and/or dryness (test out of circuit)
  14. Yeah I can't use my back when moving it, this one has 3 BNC as well ( R, G, B ) Vielleicht! But it only just appeared in my saved searches a couple weeks ago, so unless the seller updated the listing I can't say.... Au├čerhalb von MUC? The board doesn't appear all that bad from the inside the case though there are some loose floating tants with corroded legs which doesn't bode well for any nearby ICs. I haven't broken them down yet, and there are a few SMD electrolytics I want to replace. It's nowhere near as bad as the huge brown rust holes you typically see in an
