The wobble/shimmering looks like a result of the OSSC or your LCD sync - can you try another monitor LCD or ideally CRT.

Hi, What cards are they - Apple branded or generic? Cooling on these cards could be pretty average and without decent airflow and cooling the core burnt out on a lot of these cards. You may also read about "bump gate" for Nvidia GPUs of the era but this was mostly 7x00/8x00 models. Also...

Fair enough @macuserman I've seen 2018 Mac Minis kicking around cheap too. They're great Macs. I was keen to resurrect my Mac Pro as it was kind of sketchy from the start (noting hard life before) so at least it should be rock solid in use now. I'll need to check the GPUs on the donor 2013...

The other day my 2013 Mac Pro just gave up - it was having its usual sleep overnight, came to find it dead, no power, tried all the tricks. Pulled it apart replaced the PRAM battery (which was measuring 1.5V), PSU red LED comes on with nothing else connected to it. Clumps of dust through it...

It looks like a hardware fault with the card, most likely the VRAM. Are you using the standard video card (has upgradable RAM you can clean slots or switch around with known good VRAM SIMMS) or AV HPV card (soldered RAM can't remove). Also inspect both cards for damage/loose pins

Wrong link? Goes to an LGR YT video. If you can reproduce it on two monitors GPU would be at fault

I’ve got a Buffalo 500Mhz G3 in my beige G3, it’s the perfect match works well - once you go past this speed in early G3 desktops it’s a law of diminishing returns. Voodoo 2 would be a nice addition in one of the slots.

Hi Lastic, Looks great nice pickup. I've never found a 5x0 battery alive in all my years of collecting, even with restoration. There are some guides on here listing various success with replacement cells but hard to get right. The PCMCIA adapter fetches a pretty penny if found loose. I'd...

These boxes are definitely not suitable as replacement for 68-pin ROM sockets in SE/30s are they?

Wonderful thanks @Mike68k ! Can't wait to try it on a stock-ish SE/30 and seeing what sort of further dithering/optimisations come through.

I've never heard of the SE/30 stock ROM not detecting 16MB SIMMS; once you get the right stuff it should be OK

Coming from a Mac world, the mouse card is useful to me in an Apple II it'll stay. If you are running an Apple composite CRT and don't mind modern enhancements like these, I'd thoroughly recommend the ESP32 card. Coming up is reportedly an Apple II emulator which runs 4X the original speed...

Yeah that's not factory :). Take it apart and see, someone has done it and it probably worked like this for years, it might be a faulty DC jack that makes it switch off when moved, over this butchery.

Hi, What other Macs do you have at your disposal to fix the software issues? 1) not sure 2) try to clean the lens with a cotton tip dipped in IPA, failing that take apart the 1400 optical drive and dial up the laser strength pot 3) Any generic CF-PCMCIA card adapter will work, usually...

Back ya go to check your recaps! Marginal trace somewhere, some vias there look light on solder.
