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...

I can confirm that dumping the SCSI2SD to the BlueSCSI using Initiator Mode works just fine. I'm doing so right now and am getting 1 MB/s transfer speed.

Couldn't you just put the BlueSCSI into initiator mode to dump the contents of the SCSI2SD into an image file?

An SE/30 I recently acquired on eBay had a Pivot expansion card loose in the chassis. I connected it to the logic board and found it perfectly functional, though it's seriously lacking in capability because it has only 256 KB of RAM on the card if I'm adding correctly (two chips of 256 kbit x4)...
