Anyone have any knowledge on the SE's logic board, I'm getting a steady 5 volts from the ADB port, does the protection circuitry stop the data line instead? @Kai Robinson @Bolle

What should I try next?

If it's not the RF block then what's next to check?

Awesome work!

Was referencing this guide https://vintageapple.org/macbooks/pdf/Troubleshooting_Your_Macintosh_1992.pdf Covers the issue from page 198. If it's not the board then my keyboard and mouse could be toast...

I've been using the repair guide by Douglass High, I did a check on the RF choke/fuse and it tested good on each pin, he said there was an additional Pico fuse near it but I'm struggling to find it. I'm guessing it's either L1 or C12, they don't look like typical fuses but I went over them...

I'll give the fuse a quick check on the multi-meter, just need to find where it is online.

Yep the question mark flashes with no boot device attached. When it's stuck on welcome and I press the interrupt switch, I tried twice on both ports but I still can't type anything. I think the fuse needs to be dealt with before we move onto debugging. If it's safe, I can jump the circuit with...

I've tried my System 6 hard drive and my FloppyEmu. If the SCSI bus is broken then I'm not hopeful, it's hard enough finding ROMs and controllers for a decent price :/

Has anyone had this happen to them and what component was broken in your case?

Hi, My SE stopped working properly a few months ago, it won't boot system 6 or 7, freezing on the welcome screen. It can boot System 4 but the mouse doesn't move at all. I've tried replacing the power supply with an ATX unit that has enough amps for each rail, but still no change in behaviour...

Hello 68kMLA forum!, I started a new github page to discuss ideas for a modern 68k accelerator for old Macintosh systems, this will begin with the Mac SE + SE/30 - but I hope that if the project gains any traction, that others might want to port the designs to other Macs, newer or older, than...
