I just had another episode with my 2088 BridgeBoard:

 While I was working around the back of my machine, I happened to wiggle the
external floppy cable coming out of the back of the BridgeBoard, shortly
afterward, a message appeared: error in internal stack - shutting down
(sorry I can't remember it exactly). After that no more bridge, I tried
rebooting via ctrl-alt-del several times then ctrl-amiga-amiga several more
times (since my hard drives are on the *bm side, I lose it all when the
bridge goes). Also tried cycling power, still dead bridge. Finally, I took
Amiga apart, reseated the bridge card in it's edge connector, and pressed a
couple of socketed chips in tightly. After I put it back together, every-
thing worked fine. This sort of thing has happened before, although it has
been a few months since the last time.

 I have one of the early 2000 / bridge units, I had to take a file to the
edge connector of the bridge before it would seat in the motherboard without
requiring excessive force (the connectors are misaligned). Possibly all the
warping of the motherboard that I did when I was following the computer
store's advice ("just lean on it!") has broken something. Anyway, if your
bridge starts getting strange, you might try reseating it.

 Oh, about the file: Think very carefully before you do this! by misaligned
I mean that the two edge connectors are closer together on the card than
the matching connectors on the motherboard. A little (VERY little, too much
and the fingers won't match) off the edge of the one of the bridge board's
connectors let me plug it in without having to act like Rambo. I am NOT
recommending it! The correct thing to do if you buy a product that is not
right, is to exchange it for one that is.
