SE/30 Questions
Jim Van Verth
black and white stripes on startup. Reading up on this, it appears that
this is either a) the battery b) the RAM and ROM connections or c) a faulty
analog board. I've already tried cleaning the RAM and ROM connectors.
Pulling the battery has no effect. Before I go spend money on a new
battery, I want to check the analog board.
I do have a working SE, and my understanding is that the analog boards are
the same. So... is there any difference between a Mac SE and a Mac SE/30,
other than the logic board? If the analog board is kaput, I'd rather just
install the SE/30 logic board into the SE case -- it's a little easier, and
it's only a temporary measure anyway.
One dumb question: would plugging a Imagewriter printer power cord into a
Mac SE/30 have any adverse affect on it? I figured they were the same,
other than one is straight and one is an 'L' shape, but you never know...
The Mac was acting flaky beforehand, but I just want to be sure for future
reference.
Thanks for any help.

The most likely reason is the battery. The most simple test is replacing the
battery. The most difficult task is testing the logic board...

What about the battery of the SE, why not put this one into the SE/30?

No, they are functionally the same.

The SE battery is soldered to the motherboard. So I picked up a new
battery, but it still locks up. I also found some other threads about
the SE and SE/30, and it looked like I should be able to swap the logic
boards. I did so, and that doesn't work either. So it looks like it's
not the battery and not any other part; the logic board is faulty
somehow. Considering that I found some mouse turds inside the case, I'm
thinking that storing it in the basement was not a good idea...
Thanks,
Jim
