UGH the via tests OK for continuity. It's the D29 data line. Maybe something's leaving it floating and touching it gives it a nudge. UGHHHHH. Hooray for schematics I suppose 😐git.j-w.au/james/Macintosh-SE3

A while ago I edited the redrawn Macintosh SE/30 schematics to make them easier to read. (Easier for the way my brain works, at least!) Less lines, more labels.

Maybe you'd like them too, so I'm sharing them here: git.j-w.au/james/Macintosh-SE3

I found the bad via!! (sound on for the boot chime!)

(That's just a sewing needle in a pin vice)

Been working on this se/30 on and off, for months. It won’t boot. No startup chime.

Anyway, I just turned the board upside down and a couple of the custom DIP chips just… fell out of their sockets.

Probably unrelated ¯\_(ツ)_/¯

Pretty crusty. Any recommendations on an ultrasonic cleaner?
