@RetroTheory , I have an IBM 5155 on the way and would love to swap the CRT into the one of my SE/30s. Do you have any details on the procedure? Do you keep the yoke with the CRT tube and re-wire to the analog board? Remove the yoke from the Mac CRT and install it on the 5150? Any advice you...

Unless I'm missing something, the HDI-30 was a SCSI connector. Not sure you could use it to connect a floppy drive. Here's the Pinout numbering for both (noted at top of the "Ports and Pinouts" document "The pin numbers shown are for the connectors attached to the ends of the Macintosh")...

This is a really cool idea. Is the TechStep just a device that is sending and interpreting commands over the serial connection? It would be really cool to pair this with a usb-c to serial cable (plus mini DIN 8 adapter) with an iOS app that does all the things the TechStep does. It appears...

If you need a GLUE chip from a Iicx, I have a battery bombed board where the GLUE chip and the SWIM chip look to be in pretty good shape. Unfortunately, wasn't able to test this board because it had so much battery damage. But the Glue chip looks good. The SWIM chip could also be usable...

Sorry, I don’t know the symptoms of the incorrect diodes. I replaced mine before I transported anything. I think Colin was saying you’d get a Simasimac (which I always thought was different than horizontal bars, but others can chime in if that is a type of Simasimac). So I think it may be...

Yeah, that was the spare board I got from your buy. I did do the diode replacement with the ones you sent after the fact. I didn't run into the horizontal bar issue with the other board, but may be worth double checking those. I did notice some not thoroughly cleaned flux on the diodes that...

OK, DM me your address. I'm hoping to be able to mail them out this weekend. Just been busy getting ready to send two kids off to college.

OK, my order of the larger inner diameter parts finally arrived. The problem is I have 8 "orders" on here and I only bought 7 in this order. I believe someone (@Markintosh or @tom_B ?) mentioned they probably only need one, so that probably will mean I have enough to send to people who...

I also have a 2.1x5.5 that I could use for the 20v if that works better. But if there are other adapters and having a 2.5x5.5 on each gives you more flexibility, I can do that.

Are you ok with a 3d printed case or want me to get a quote for getting resin versions printed to match the PB5xx version you got? And are you thinking one 20v version and one 15v version, both with the 2.5x5.5 barrel jacks?

Yeah, my model was more optimized for the resin printing I was planning to do, so it is probably not as good for FDM printers. I also found this model, which looks like it may be better suited for FDM printing. Also, with its thinner outer wall, I wonder if it would look better with the clear...

Sounds good. Let me know. I don't have any generic 15v resin cases, and JLC3DP prices have gone up a bit. I can 3d print one myself, or get you a quote for a resin one to match your other. I also just realized I have no more 15/20v usb-c trigger boards, so I'd need to order some more of...

My initial “universal” power supplies were barrel adapter versions that I could change the tips out on. Along with an adjustable DC power supply. But these were so much smaller I ended up making dedicated versions with these for each of the laptops I have. I could make a 15v barrel jack...

The fit’s very nice. I’m not home right now but I feel like the extruding part is nearly flush with the back of the case.

The full size SD card for the BlueSCSI v2 is much easier to retrieve. Also, I use a microSD card and an adapter, so if something were to put pressure on it and have it break, hopefully it would be the adapter and not the card itself. I’ve broken 2 microSD cards trying to get them out of the...

Yes, I posted as a remix to @PotatoFi 's version on Printables: https://www.printables.com/model/1173988-usb-pd-trigger-card-case

If I had to guess, they are having a shortage of that print material and it isn't that it is sold out. Likely their daily capacity is set to zero. That is what I ran into when they were trying to phase out JLC black resin. Unfortunately, I just had to keep trying to submit payment until they...

I've found that JLCPCB actually does do somethings like that. When I was trying to print my Lisa mouse with the Lisa logo, I went back and forth with their engineers to get it in a printable state. I guess when I combined the parts in TinkerCad, the logo was floating above the mouse. They...

I used the Printable model (although I combined the two pieces myself in TinkerCad, so the combined version @Dave928 used should be very similar to mine in terms of fit. It will be interesting to see if the clear resin print from PCBWay is a better fit. From my measurements, they seem to be...

So, I just tried to measure my resin print with my cheap calipers and the round hole seems to be pretty much spot on at 6.0mm. Which is the same measurement I get on my original. I wonder if there's something else about the clear resin that is causing it not to go on (surface tension /...
