I just picked up a non-functioning Lisa 2 (which was
an upgraded Lisa 1) and
have lots of technical documentation, but nothing on the motherboard and
wiring between powersupply, video and motherboard/cage assembly. I'd like
to avoid tracing it all out if this info is available.
The Lisa/Macintosh XL Do-it-yourself Guide has some good data on the Lisa,
but no schematics. I believe I have technical data on the Lisa, but it's
buried :(
Also, it appears that one 120 pin socket on the
motherboard is missing a
connector pin, and there is some amount of blue corrosion on the tops of the
other connectors. What's the best way to clean off this kind of (light)
corrosion (oxidation)?
The blue corrosion is usually caused by the clock battery on the main
board (the one you see when you open up the back) that goes bad and leaks
all over the damn place. Some good suggestions have come up in the past
regarding cleaning it up, so I'll let the experts chime in (I know I have
that info saved somewhere).
It appears to me that the motherboard socket that is
missing one pin will
need to be replaced. Anybody have any recommendations on how to best do
this? The motherboard is a four layer board. I have soldering/desoldering
experience, but I've never tackled an item with this many pins on a 4 layer
board before.
Find another Lisa :) and use it for parts.
