So, I have finally started trying to salvage the LC form factor machines from my shop haul last December. I was able to get two boards that weren't destroyed by the battery or flooding. Unfortunately, neither would initially boot. On the first, I was looking over the board after my recap, and...

So, I replaced the DFAC and the sound was back... until it wasn't. The only change was the power supply. So I tested the voltages and they matched. Now I think I assume I'm going crazy, so I switch back and forth the power supplies and I get inconsistent results. I think maybe it's another...

Another minor update. I moved on to assessing the Quadra / Centris 610 machines. While it looks like I had 13 of these machines, I think I'll only get 5 or 6 working machines out of them. However, as I was opening up the machines, I ran across one of the machines I photo'd as a "lowlight" of...

Is that 3D printed? I feel like it's painted, but then I also am trying to figure out what's going on with the bevel on the bottom lip of the floppy opening!

I’ve only mounted my BlueSCSIs in the expansion port, because despite having a ton of SEs and SE/30s, I have no PDS cards (actually I think I have one Radius Card, but that machine is in storage. Hopefully someone else has a model that will work for this.

It definitely is possible. See my note above about the Mac Plus CRT neck pins not working. I'd grab one from a newer SE machine to be safe. But it worked quite well.

OK, I just went through the process and am happy with the results. I'm not using my MacEffects SE/30 super regularly and it clearly isn't my "true to the time period" machine. Here's the results, and I'll share my experience with the switch. after. So, my plan was to do a "swap", but I...

@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...

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?
