Thanks for the info @David Cook ans @zigzagjoe !

How would this manifest on the IIfx? I haven’t seen any issues on my IIfx running the NuCF yet even under a lot of benchmark testing for you a year ago.

That’s odd. Have you tried ruling out the video card by using another?

I once had a scsi issue which I also resolved via a PRAM reset. But didn’t get the graphics issues you are seeing. Looks like you have a desktop wallpaper extension running. Do you see the issue with it disabled? There is also a known issue with the 8*24 GC card and System 7 with drag and drop...

@croissantking linked my thread from a few years ago, but yes, I transplanted a 14” Samsung LCD into a 16” Macintosh Display. Made a curved acrylic “glass” for it also. The result is in the linked thread. I was going to do another at some point for a broken 13” M0401 trinitron I have. But it’s...

Cool! So now we should be able to patch the ROM to remove the memory test.

I’ve got one I made and one original recapped. The recapped one was working fine for a while but then all of a sudden stopped working. I had resealed the plastic housing so need to open it at some point and see what happened inside.

Ah yeah, I'm seeing a steady ~5V coming from various points (connectors, psu, logic board, etc). I see the issue with additional 5V supplied or via termination power to ZuluSCSI. The power supply is fairly new (modern ATX) and is rated at 30A on the 5V rail. I have not measured the current but...

What do you mean by tapped? The power for the ZuluSCSI is coming off the 5V accessory connector on the power supply and last time I measured it was healthy.

Yeah, that seems difficult.

Yeah, was staring at my bench 540c and was thinking about how to save the floppy but with it in place, I don't think it will intake/exhaust correctly. I could do three holes (left exterior next to the hard disk bay and both sides of the CPU bay) and then out the floppy port. But before that, I...

Been playing with this a bit... I have three different CPU cards all of which have had CPU transplants. Card 1 - Full 040 with FPU (Freescale/L88M) without memory hack w/40MHz overclock - runs stable at 40MHz even after 3 consecutive runs of MacBench graphics tests, but no memory hack Card 2...

Yeah, my ZuluSCSIs always are powered via the floppy/berg connector. Didn't help me :( I got a working spinning disk from @techstep so when I get a chance, will test with a real drive to see if my issues are caused by the scsi emulation device.

I used JB Plastic Weld to get the overall shape. Then after it cured, grinded it closer to shape with a dremel and then it was sanding the rest of the way.

Not going to try since it’s working great. :)
