  1. Yeah the 2uf one is still there. I'm probably less concerned about that one compared to the RIFA ones.
  2. I would strongly recommend learning to read the values of each capacitor and then place your order based on that. While logic boards will all USUALLY be the same, PSUs and analog boards (if you have any of those) may have different vendors/models/revisions and the caps list will vary. This might not really apply if you're only ever going to recap one single machine but I think I'm learning a bit more about electronics as I continue recapping everything I own.
  3. Finished my recapping and nothing blew up. Some of my film caps were much smaller than the old ones being replaced so what I did with those was mostly had 1 leg lined up with the hole and the other leg bent a couple times to fit the second hole. Had to make sure I ordered one with long leads. I have a video of all this but it'll take a day or two to finish it. Some Digikey part numbers I used: 399-13014-ND - KEMET 0.047uf 399-5876-ND - KEMET 4700pf 399-12519-ND - KEMET 0.1uf
  4. I'll be recapping mine this week. I accidentally ran out of solder and some of the film caps I ordered aren't the best fit so I'm going to try some others. I can probably remember to update the thread if it works or not.
  5. I didn't order a 2uf film cap for mine but here's an example of the 0.22uf capacitor I'll be using in my PSU: https://www.digikey.ca/product-detail/en/kemet/R75PN32204030J/399-12762-ND/5731253 I believe I used this same type already in my IIgs.

    A/UX running on SE/30

    I also made this one based on my experience: https://wiki.preterhuman.net/Newbie_Guide_To_A/UX_(Apple_UNIX)

    Re-cap gone wrong.

    Every LC power supply I've taken apart so far has had cap leakage, even the ones that still worked. On the plus side they're the easiest power supply to work on in my own experience.
  8. Unfortunately I haven't tried mine out yet so I'm not completely sure on the details yet. I was probably going to try ProTools 2.0 which is for 68k and I'm assuming supports the Nubus boards. https://macintoshgarden.org/apps/pro-tools-20
  9. MacOS stops showing model numbers after 7.1 I believe. The very first 7.5 might still do it but I've never seen it on anything beyond 7.5.x. The Digidesign stuff more than likely is for audio recording to interface with something like Protools. The cards are mostly useless unless you also have the external box with all the inputs and outputs. One computer I got recently had a single Digidesign Nubus card but also came with the external rack unit for the audio hookups. The cable is physically the same as external 50-pin SCSI I think (not sure if any pins cross over weirdly).
  10. I had a similar problem on my StarMax 3000 where after sitting for a long time it only powered on once then seemed to be dead. Had to use the motherboard reset button a few times but since then it seems to power up normally each time I try. I'm also running it without a battery.

    Early Mac LC proto?

    I picked up a bunch of LCs recently and one seems to be a very early board: The very large capacitor and reset switch were odd as the rest of them weren't like this. The case it was in is otherwise a normal production LC.

    Can you run some sort of application that tells you the clock speed? Wondering if this is one of those 33mhz LCs that I'm assuming are probably just a factory overclock of the 25mhz board.

    Apple Set Top Box

    You got my hopes up there... Threw a full 040 in but no change. I'm probably going to be stuck with figuring out ROM disassembly.

    Apple Set Top Box

    On a whim I ordered a gglabs 2mb ROM with a Quadra 840av ROM image... Unfortunately it does nothing. I was hoping it would be close enough to the AV hardware and give me TV output like on the AV Macs. Now I need to maybe figure out how to take my original STB ROM dump and add to it, then burn it to this SIMM.

    Apple Set Top Box

    So I've already got this booting off the drive from my LC 475... There's no video so I dropped a copy of MacCheck in the startup folder and then used command-I to bring up the brief info box and took a screenshot. Pulled it off the drive after. Since I can't actually see what I'm doing, it's tough trying to make this thing display good detailed hardware information...
