To clarify, I mean converting an ATX power supply for use with a 128k/512k/Plus. As much as I understand, the SE & SE/30 use wholly different connectors on the logic board.

I've used these in the past for the 128K / 512K. (mouser) (Molex 09-50-3111). I use one for my ATX to Compact logic board adapter which includes a breakout for RGBtoHDMI.

That's my first time seeing that — thanks for sharing!

Basically a visual inspection — if I could see yellow glue I scraped it away. If I recall correctly, I used a plastic spudger for most of it and a flat head screwdriver for uncooperative spots. No chemical baths, just prepping the surface with 99% IPA. edit: It's worth noting, applying the RTV...

Interesting, I see. I don't think there's any harm in cleaning the headphone jack (or outright removing it for testing purposes). If you're open to a little fringe experimentation you could connect a speaker directly to the connector on the logic board. edit: for clarification, the red circle...

I have a lovely Quicktake 200 and Smartmedia card but no way to upload the photos to a computer. I've purchased two readers — an old HP Smartmedia reader which turns out only supports 3.3v Smartmedia and a MicroTech CameraMate. Unfortunately, the CameraMate doesn't seem to power on, even with a...

Great job, the colors look beautiful!

Here are all four sides of the "resealed" flyback.

Exactly this. For some reason, I often find older macs have dead speakers (with no obvious sign of damage). I have a “new to me” 512k with this problem right now.

Not exactly plastic tabs, but I've used firm steel mesh (Amazon) to reinforce a shattered HD20 and can confirm it works quite nicely.

I personally have a Hantek DSO5072P (Amazon) which is quite nice but I have been considering a Hantek 2D42 (Amazon). Coincidentally, a few of us on the Open Retro SCSI discord server were discussing this 2 weeks ago and a few members were fans of the "5012H" oscilloscope (Amazon)

I don't think there's anything particularly special about this brand, but I picked up American Sealant, Inc.'s 502 "High Performance" RTV Silicone locally (Amazon) (Datasheet). In order to prepare the flyback I carefully cleaned every last speck of yellow glue from the housing and then...

Adrian's preset is for the Macintosh Classic, which seemingly uses a different signal schema. I have a preset which I've created for the Macintosh Plus (it also works on the 128k and 512k). I haven't tested this on the SE or SE/30 yet. Save the attachment to /Saved_Profiles/6-12_BIT_RGB/ on...

I was waiting for you to post your solution before I said anything. I had this problem on a mac, in fact after watching JWD's video I now check all of my analog boards in complete darkness as part of my standard induction process for "new" (to me) machines. One had a faint blue glow and upon...

I purchased this Mac 128k logic board knowing it wasn't working. I've poked at it a little over the last 6 months, which includes: Building a 4164 DRAM tester and testing the original DRAM. I found 2 were faulty but ended up replacing them all. Swapping the LS166 @ F14 & F15 (example board...

@MacintoshLibrarian had a great video about MECC, I learned a lot from it and recommend it.

Dang, that looks great!

Excellent use of this format, Eric. Very nice!

Absolutely, though I'm not sure how hard it would be to cut to the template? Either way I need to finish the template. It would be really cool if someone could find a company that can cut the design and ship it — and even more cool if they can have an "order now" page for specific designs, like...

Thanks for bumping your question, I meant to get back to you but it fell off my plate! Does this help?
