Slaton Computers on eBay is pretty good. I have their simms in my Quadra 700s and one of my SE/30s https://www.ebay.com/itm/176333431088

Sure, and the point I am making is that bus speed of the SE/30 is definitely not the problem since the IIvi and IIvx also have a 16 MHz bus. I am not trying one of their ROMS, but instead a IIci rom which ZZJ says works.

Yes, I just ordered one from GGlabs and asked them to write a IIci rom.

I don't think the bus speed is an issue, because this card allegedly works in the IIci, IIvi, and IIvx. I don't have a IIci ROM on hand. Any way I could buy one?

I don’t have the skill set to reverse engineer the ROM. I’m curious whether it might work with a IIci rom in an SE/30?

I searched far and wide for information on the Interware Booster CV 40 for the Mac IIci with the SE/30. I wasn't able to find much. I bought one from Japan and tested it with a Twinspark adapter. I can confirm that it does not work on SE/30.

I replaced the PSU with another unit and everything works fine now. What a pain though.

All readings are 0.0 V until the things springs to life a couple minutes after being turned on. Obviously a power supply issue- but what specifically?

Logic board was recapped by a previous owner. I'll need to leave the machine unplugged overnight to get the no chime scenario and check it tomorrow.

+5.00 V and +12.3 V read fine The -12.0 V gives me 0.0V Note that these readings are after it has booted up

I have an SE/30 that turns on very slowly. I don't mean the memory test, what I mean is that when I flip the switch it sometimes takes a full minute or two before the chime occurs. It is almost like a capacitor in the power supply or on the analog board needs to charge up or something. Is...
