Checkerboard pattern on a Mac Plus

[Sean Caron]

Ah, the ole cold solder joint, cause of many problems ... interesting to
see that failure mode, though; my first guess would have been something on
the digital board... I've got an old Plus here myself, as well as an old
128/512 with a [failed] DoveSnap ... I hadn't powered either of them up in
well over 15 years and I was surprised that both of them came right up with
practically no problems; perfect display, no Sad Mac ... the floppy on the
Plus is stuck in looping eject mode but I understand that is a fairly
common fault for those drives of that vintage that has known fix ...

Honestly I could do to clear either or both of those systems out ... they
are mostly just taking up floor space ... I have a complete, mint condition
Mac SE FDHD that fills that niche for me :O Much easier to work with
something that's got a Superdrive in it, and the built in hard drive is a
real space-saver ... anyone interested in some old Macs near Ann Arbor, MI?
Drop me a line and you can stop by and grab them sometime :O No keyboards
or mice incl.

Best,

Sean
