Your Mac may not be as dead as you think.
I looked up these codes in my copy of "The Dead Mac Scrolls" (a
wonderfully useful book if you can get a copy.) They don't describe
this code for the Mac SE, but they do talk about the equivalent code
for a Mac Plus:
Symptoms: On startup, the computer bongs and you almost get
to the desktop, but then you get a sad Mac with errpr cpde
Typical history: The Macintosh Plus (or 512Ke with SCSI
upgrade) is connected to an external HD 20SC or other hard
drive. If you disconnect the hard drive and boot from a
floppy, it works OK.
Probable diagnosis: The hard drive has a bad partition map
Solution: Boot the computer from a floppy disk, wait for the
desktop to appear and then turn on the drive. Use
third-party SCSI formatting software to repair the partition
map (this won't always work.)
If your SE has an external hard drive, try the same thing.
If your hard drive is internal, see if booting a floppy will get you
to the desktop anyway, then try a third-party format utility. I've
had good luck with Anubis, by CharisMac:
If you can't boot a floppy, open the case and disconnect the hard
drive. (I assume you can safely do this, since you're talking about
taking it apart for parts.) Then try booting a floppy. If that
works, all you have to do is replace the hard drive.
Anything with a 50-pin SCSI connector should work, although versions
of MacOS compatible with an SE will limit you to 2G per disk partition
- so you'll end up with a lot of drive icons if you use any relatively
modern drive. The Apple disk utilities won't format a third-party
SCSI drive, but third-party programs (like Anubis) will.
Other third-party disk formatting programs I have used include LaCie's
and FWB's Hard Disk Toolkit:
My experience with all three of these programs is based on old
versions. I haven't used the current versions of any of these.
Current versions of Anubis and Silverlining still claim to be
compatible with everything from a Plus and up.
The current version of Hard Disk Toolkit says it requires a Power
Macintosh, so it's of no use to you.
