SE no ADB

[bibilit]

I have a double 800 k SE with no ADB, i know the problem is coming from the Logic Board, using a different board works great.

Any idea where to start with ?

There is a Fuse on the board, don't rememeber its name or location, but it is close to the ports

I've heard hotplugging (or unplugging/plugging in a keyboard/mouse while the computer is on) can blow the fuse. There is a fuse for it somewhere on the logic board. Unfortunately I think you need a soldering iron and solder to properly replace it.

Any idea where the fuse (if any) is located or labelled ?

In not aware of the SE being fused when it comes to ADB. The SE/30 is the first design that I know of where it was implemented.

But you say using a different keyboard works great. If a different keyboard works, its not the motherboard. Or is that a type-o.

Unity, I think that's a misread. Bibilit says it works with a different board, (not keyboard) so the issue is definitely on the logic board.

This thread from 2012 may be of help: https://68kmla.org/forums/index.php?/topic/17894-se-with-dead-adb-ports/

No go, tried to run a wire, but this is short circuiting the rest of the connections.

Should find another Board or filter.
