@Volvo242GT It's connected to a IIci. Best info I found suggests that the display works with the built-in video: https://machut.net/mirrors/radius.vintagebox.de/RadiusQA/mono_pivots.html I have the Soft Pivot 3.2.1 control panel and driver installed as well as Dynamic Desktop 3.3. Tried system...

I recently got this Radius Pivot model 0361 and, after much finagling with the DIP switches on my VGA adapter, got a decent picture except the top of the display has some horizontal lines and the shadow of a flipped menu bar. Anyone seen this before?

I have dual 16GB 5060 Ti's I use to run local LLMs with ollama. They can do stuff, yes. I've mostly used them for Python web development and had best success with Qwen 3.6 27b and Gemini 4 models.

I ran the video and logic board tests a few times and everything passed. I also got out one of the other IIx boards and it does not exhibit the same issue like I remembered, so that at least isolates the logic board as the culprit.

Well, at least this makes me feel less crazy! I pulled the batteries, reinstalled and booted into the disk image you provided: glitch remains. I jump started it with no batteries installed: glitch remains. I attempted to manually reset the PRAM from software (opt+cmd+shift open control panel)...

Here it is booted from your disk image:

@David Cook what installer have you used with your Mac II's? I've been using the Legacy Software Recovery CD from https://macintoshgarden.org/apps/apple-legacy-software-recovery-cd, usually installing the system from SheepShaver before moving the disk image onto an SD card for the BlueSCSI.

I had time to look at this again last night. I borrowed a Floppy EMU from a friend and booted from the install disks for Systems 6 and 7. The scramble remains when booted from the floppy on anything other than black & white for grays or colors:

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...
