I'm almost positive I tried Snooper when working on the same machine that had the RTC issues, and it did not fail any tests. However, I'm not sure exactly which Snooper version I was using. APD's "Logic Board Components" test should finish quickly, unless the RTC test times out and spits out a...

One word of caution about MacTest Pro, though this is purely anecdotal: It does not seem to test the RTC, including the 1hz timer. Apple Personal Diagnostics, despite its vague and unhelpful output messages, does test the RTC. If the clock is running slow, if you notice inconsistencies in cursor...

One of these was the second computer I ever saw, and the first Macintosh, so I have above-average nostalgia for them, too. Especially the way the display would dance around from degaussing, when waking one up.

If the physical connector/pin order is ever the issue, but you know the fan is electrically compatible, you can also use a very small, flat screwdriver to press down on the exposed, angled parts of crimped pins on the new fan's plug, then firmly (not with excessive force that'd rip anything, of...

Disappointingly, it seems like flashing a Dell-branded OEM Rage 128 Ultra with the PowerMac Rage 128 Pro VBIOS does not automagically work. I didn't expect it to, but it was at least worth finding out.

This in particular got me good.

I just looked at the commit history, specifically the "instrctions.docx" [sic] file that was later deleted. This is blatantly the work of an agent or LLM.

If you've got that much memory working with a IIci, then at this point I have almost zero doubt that my problem was the particular SIMMs I used. Only makes me more curious about the specifics of OP's IIfx.

Are you using the stock IIfx ROM and a reasonably small amount of RAM? I've gotten A/UX 3 to freeze while booting on a IIci before by either using a ROMinator SIMM or >32 megs of memory. Both would get it stuck for seemingly different reasons.

Accelerated video and an Ethernet card would probably be the most accessible. I was personally able to get an E-Machines Futura SX and an Asante Ethernet card for very little, a few months ago. There are accelerators with adapters for the CPU socket (if present), and of course Radius Rocket...

I could've sworn SE/30 logic board (and IIsi?) was six layers, and the IIci and IIcx's middle layers were the ground/power planes, with the logic conveniently on the visible sides.
