I have a Mac SE purchased last fall, with two internal floppies and a Mirror
40X Magnet hard disk. Here's the problem:
1. When I press the interrupt button on the left side of the Mac (the one
that throws you into the built-in debugger), I get a System Error, ID= 28,
which is a stack overflow error.
2. I've been informed that if this happens with 5.5/4.1, it is very likely
a hardware (ROM) problem. Sure enough, that's what I was using when it
happened: 5.5/4.1.
3. It does NOT happen with 6.0/4.2, however. Works perfectly.
4. Four days ago the hard disk, running 6.0/4.2, crashed horribly, with
buzzing, Indian blanket, the works. Wouldn't even reformat. I just sent
it back for on-warranty work. The first couple of times it crashed, though,
before the noise/blanket started, it gave an (guess...) ID= 28 System
Error.
I've been advised against hooking up the repaired hard disk until this is
resolved. Any and all comments would be most welcome, before I go out and
pay for a repairman's new ski boat.......Thanks in advance,
