@phunguss I only have the one PCjr and the one PCjr display, and the proprietary connector means I can't try the display on another computer. I do, however, have the adapter that allows for regular CGA displays to be connected to the computer, though I'm not really sure where it is. Also, the...

The video output on my PCjr looks like it's losing horizontal sync whenever I reboot after it's been running for a while. When it happens, I usually have to leave it turned off for at least 20 minutes. It's been doing this since I got it in 2021. I have recapped the motherboard (and maybe the...

My Quadra 650, which was severely battery bombed but amazingly still functions after quite a bit of cleaning, has two 512 KB VRAM SIMMs from Garrett's Workshop installed, but the OS isn't offering me thousands of colors at 832x624; it only offers me 256 colors. This points to a problem with...

Though it's a touch tricky, this is designed to be levered through the NuBus slot opening and then pulled flush with the outside of the opening. It looks like you were just trying to butt it up against the inside of the opening. If you lever it through and then pull it back snug, the bit that...

I decided to play musical hard drives and move the BlueSCSI from my SE/30 to the Quadra 650. The mount I designed works pretty well, though I probably should have made the SD card opening just a bit bigger. The important thing is that it works.

I'm satisfied with the alignment and stability using my mock-up in the Quadra 650. This design simply modifies the available models for the NuBus slot cover to remove the clips, add an SD card opening, and add a bit of length to fuse with the universal BlueSCSI v2 mount. This is then attached...

I've posted this over on GitHub at https://github.com/jimfrob/AppleCD-600E-Bezel/tree/main. It includes the FreeCAD file for anyone who wants to make tweaks.

Just so everyone knows, I haven't given up on this. I have a rough prototype of the mount itself, but I haven't gotten to the bit that holds it in place yet as I've been focusing on recreating the bezel for the AppleCD 600E. I expect to have that model finalized shortly. When it is, I'll make a...

Looks like Google AI let me down yet again. It told me I should use the Macintosh II-family connector shields for this project. While the model I made should work with a Macintosh II, it does not work with the Quadra 650 because the NuBus expansion ports are of a different design. I'll have to...

Here's the rough mock-up using a 3D printed facsimile of the BlueSCSI PCB. I'll be able to get a picture of a test fitment in the Quadra this evening.

I hadn't even printed the mount because I don't have a spare BlueSCSI. But I'm printing it now, and I'll even print a facsimile of a BlueSCSI so that one might see how it all fits together. I have an awful lot of filament in a color that turned out to be not so great of a match for the projects...

Even though nobody asked for it, I'd rather have the information out there for any poor fellow who also has no drive chassis. The design files can be found on GitHub at https://github.com/jimfrob/Quadra-Centris-650-Drive-Chassis

I searched a while I didn't find any existing model or project to mount a BlueSCSI v2 into a NuBus slot, so I knocked one together. This is a rather niche thing that may or may not be useful to anyone. In fact, I myself will probably not use it since I'm pretty happy with the SCSI2SD in my...

I'm now fully up & running with the floppy drive. Thanks again to @phunguss for providing the measurements that got me where I needed to be. If anyone is interested in my design files, let me know and I'll upload them to GitHub. My design for the floppy drive sled probably won't work for...

My iMac has a strange issue where the image will randomly shift its horizontal position. Google AI has suggested this problem is likely due to capacitors on the analog board and/or the downconverter board. Unfortunately, I've been unable to find a definitive list of caps I'd need, and I'd rather...

It may not be perfect, but it'll get the job done. Now I just have to finalize the design of the floppy drive sled and print it.

Thanks for that. I'm not quite sure I'm willing to sink another $50 (the shipping is more than the item o_O) into this Quadra. It's a pretty rusted out hulk because of the battery bomb. I've already spent too much on it just to get a power supply & processor. We'll see how my poor 3D modeling...

Those are some detailed measurements. Thank you very much! I do believe I'll be able to knock something together with these.

That's pretty much exactly what I need. If you could get me the measurements of at least the front half of it, that'd be awesome. My Bambu P1P should be wide enough to handle the full width of that shelf since it looks to be only about 230 mm. I'm not too worried about having the PSU mounted on...

I am still needing either the original drive mounting chassis or precise measurements of it. I've about given up on putting in the CD-ROM drive as the awesome bezel models provided by Ron might not work with my drive. But I do still plan to have the floppy drive, and getting precise measurements...
