I should point out that after I installed the thing, I started getting
occasional bombs with ID=10 and bong/reboot problems. It was much more
prevalent when the system was cold, or when (for some strange reason) I
inserted a floppy disk.

I pulled the Mac apart last night, after it decided to stop working with a
sad Mac 3FFF (whimper). 

what had happened was that when I installed my Dove 2 Meg memory upgrade
+SCSI, I had slightly pulled the SCSI board loose during installation
because the cable Dove uses to go from the SCSI daughter board to the
outside world is VERY short. This didn't become a problem until I started
to use the SCSI board, of course. Reseating the boards and and being VERY
careful with the cable seems to have solved the problem. (note: this
definitely wasn't a jasmine problem...)

So, a couple of warnings if you're using the Dove upgrade (or any daughter
board on the Mac card):

1) be very careful during installation that you don't pull on a cable 
	that can unseat the card, since it uses a pressure hold and not
	an anchor screw (mutter...)

2) You might want to check the daughter boards every once in a while. With
	all the heating and cooling going on in there, anything that relies
	on friction and pressure to stay seated is going to creep, and
	eventually you'll start glitching out. If you take a little
	preventative maintenance, you can save yourself a crash in the
	middle of that critical project.
