Here are the ROM SIMMs I have: I attempted to reinstall the system tonight a few times, but never got to where the highlight wasn't glitching. Do you think I should be installing the machine-specific software version like in the screenshot below or the "works on any macintosh family" version...

Oh interesting! I will do some more testing tonight. I have two partitions I've been testing with, one is Universal and the other, I believe, was machine-specific. So hopefully that is the culprit.

I took the Toby card and VGA adapter and put them in the IIci and there was no highlight glitching, so it must be something specific to the II(x). I have a 256k and 512k ROM, so I swapped the 256k with the 512k, but no difference.

It's 7.1 from the Legacy Recovery CD image. I also have a 7.5 install on this SD card I booted from just now and the issue is there as well. Could it be the VGA adapter I have? That's the only common denominator besides the display and the BlueSCSI. I'd have to check again, but I don't think...

Here's the result of that test:

I gave that a try just now and the behavior persists.

I think my initial diagnosis was incorrect, the scrambling is happening at 4, 16, and 256. I attempted to record the monitor changes to better illustrate what I'm seeing. Here is the Toby card without the RAM expansion, only supports 16 colors: Here is the Toby card with the RAM expansion...

I've been running in circles attempting to diagnose some garbled text when something is highlighted on screen. At first I assumed it was a RAM issue because I had been reconnecting traces on the problem board, but I've now encountered the issue on two Mac II's and a IIx. Snooper and APD have not...

Happy to report I swapped the oscillator with a new part and it's back in business! Happy #MARCHintosh!

@Fizzbinn kindly mailed me the print he made of this bezel, the results are pretty good! Here are a few shots of the jaz drive with it's original box I got it in. The disk was unopened so I don't believe this drive was ever used, the SCSI cable was still neatly factory wrapped as well. Thanks...

Wow! Thank you everyone!

I ran across this thread previously, but the models I see are for the mini tower not the desktop case: https://tinkerdifferent.com/threads/power-macintosh-bezels-9600-g3.3221/

Here's the 1.1 version of the stl file if someone wants to attempt to stitch the two models together. @Fizzbinn would you be able to provide the measurements of your bezel at your convenience?

It'd be neat to have a version of this with the larger opening as an option. I know very little about 3D modeling/printing, unfortunately. Maybe just printing the blank and taking a dremel to it is this quickest route… 😆

Does anyone know anything about the bezel seen in this photo? It's from an auction on shopgoodwill.com and I've never come across a bezel like this for the Desktop G3 case before. I have an internal SCSI Jaz drive I've been planning to use without a cover plate because the disks are larger than...
