I have never tried to boot while the machine had no floppy drives plugged in, but I do know that the interrupt-crash thing is perfectly healthy. My SE/30 would get the "distorted" simasi screen, sometimes with a delayed chime of death, if anything major was wrong with the logic board. This is a...

I have one of those as well, though I was not the one who did the recapping to it. I haven't seen anything like that, but the RAM check on boot is indeed super slow. Not sure of the exact time it took, but I do know there are 2MB of memory soldered to the board itself. Not sure if these can...

This exact incident happened to my good tube a few years ago, so I've been using the burnt up one that came with my leaky SE/30 in 2009. If the neck made a mess (mine did) then just vacuum and clean up any little glass bits that managed to break loose. As has been said, the blown CRT is trash...

Whatever reflowing and re-soldering I've done has stopped the screen from jittering around. Though it's still not perfect, there's at least nothing loose or cracked anymore. I've also fixed the centering of the picture and almost have the proportions perfect. Most of all, I'm not stretching the...

There's also Basilisk II, which is light enough that it can emulate a Quadra on most systems. Even a Raspberry Pi 3 can build Basilisk II and run up to Mac OS 8.1, though there's no JIT support in the ARM version, to my knowledge.

About the gunk on the board, I can't emphasize how much I agree about its importance. I got all of the visible corrosive stuff off after I removed the old caps about a year ago, but there was still grime hiding under ICs and such. The board always needs a good wash and dry with something...

If you haven't already, I would suggest using a continuity tester to check that each cap is working. I'm not an expert at this, but I can testify that multimeters have saved me a number of times. Are these caps all electrolytic, or did you use solid ones for the surface-mounted replacements?

That's spectacular! I've always wanted a closer look at the old portables with the compact Mac logic boards inside.

I'm still looking for the culprit, although my CRT is pretty burnt up as it is. The good news is that I put a jump wire on my SE/30 logic board and got it to work correctly again! My current soldering iron is big enough that it risks bumping into other stuff, so I will get a smaller one and...

I've checked out the connector for the yoke again, but nothing I've reflowed has fixed anything yet. I'm trying to avoid haphazardly heating solder joints, at risk of breaking something. It seems like a gentle press on that area of the board (Near L1 and the yoke connector) stops the screen from...

Yeah, I would think so. I don't want over 1000 volts surging through me.

Unfortunately, I think I tried reflowing that one once already. I'll look at it again.

Since I bought it a few years ago, the analog board on my Macintosh SE SuperDrive has suffered an odd problem, where the picture often changes scale/brightness. It happens occasionally when the machine is running normally. The picture becomes brighter, slightly wider, and about 1/3 of the screen...

For the time being, I put my verified good 400MB HDD from my SE in it, since that has all the files from when I had the 030 board installed. Everything works great; the noisy/bad HDD was indeed Quantum.

You're probably correct, it sometimes continues to spin, but it's about a 50/50 chance. Will probably put a SCSI2SD in it, or the hard drive from my SE since my SE/30 logic board is now toast.

It's not possible to do this without first inserting the floppy, because there's no system/extension to load until the HDD turns back on. Sometimes, the HDD will spin down right after it turns on, sometimes it will keep spinning and boot right away. If it were easier to switch them out, I would...

That's a relief. I've had weird boot crashes on an SE/30 before that were due to a bad solder joint on one of the capacitors.

The analog board looks fine; the whole inside is remarkably clean. However, the logic board has been recapped with electrolytic (through-hole) capacitors! I did some research, and the SCSI drive inside (HD 530) was meant as an external hard disk. It does not seem to have been reformatted or...

Earlier today, I visited a seller to pick up an old SE, wanting to salvage the CRT & analog board for my SE/30, which has a relatively burnt-in tube and a loose joint hiding somewhere. The seller told me he had recapped all of the compact Macs in his workshop, and they were all in good or...

Third-party support would have arrived faster, had the Macintosh supported its own development environment of some kind. For the first few years, it was completely Lisa-reliant, if I remember.
