If you hear that and nothing afterwards, it's a good sign; my

before or up to a few seconds after the startup chime, depending

noticeable car crash.
If it turns out your logic board is OK, do
consider trying to repair
your power supply
Another update - things got busy and I only just had a chance to look at this again
yesterday. Powering up via an ATX PSU produces a "bong" sound from the speaker,
which I'm assuming means that that the system board is at least somewhat healthy (as
I'd imagine that the tone is CPU-driven rather than some form of startup circuit).
I seem to have absolutely no DA15 connectors in the
junk box though, so I'll have to order one before I can test the video output (hmm,
unless I can severely chop a DB25...)
You *might* be able to, but it's a lot of trouble. They're
usually pretty cheap and available, since they were used on
everything from PC joystick connectors to AUI ports. Not as
ubiquitous as DB25, for sure, but not nearly as hard to find
as the Dx19 they used for the floppy port (which has a non-
standard D-shell size without a real name, so Dx19 or D19
usually suffices).
