3D printed programmers switches; Random SE/30 reboots

[Mk.558]

I'm getting random reboots on my SE/30.

The power supply has been fully recapped, the motherboard was recapped some time ago, the ROM SIMM has had the contacts reflowed yesterday so now it actually boots. Power supply voltages are fine. No visibly damaged traces or anything abnormal. Any suggestions?

It doesn't boot A/UX 3.0.1 because it just reboots when it's time to switch over into A/UX mode. A/UX 2.0.1 did kind of work but the disk image (BlueSCSI v2 external) probably got corrupted. A/UX 1.1.1 (if you have info on this problem that'd be amazing) is unable to boot on any of my systems.

Also looking for 3D printed programmers switches. I break them from time to time from forgetting to remove them from the case before popping off the cover for the 10th time in a week. Or stepping on them.

Dodgy RAM? A/UX is much less tolerant of bad RAM than MacOS is.

Repeated RAM tests pass, no indication of bodgy RAM. ... It has been fussy about RAM disks before though, but in a weird way: if a RAM disk was open, Disk Copy 6.3.3 would bomb the system. The reboots are random, even while during start up sequence.
