Latest Update...
The LC kept doing the same thing this morning. I wondered if perhaps time would be the correct medicine for the computer and turned it on (minus the monitor) before I left for a two hour choir practice tonight.
When I came home I flipped the monitor on and the 256 color mode was working normally again. Hopefully it won't relapse tomorrow (it didn't last time but given the age of the hardware there's always that uncertainty factor).
Time really does heal all wounds, including those on the logic board!
I'm still going with a theory that something interfered with the board when that SCSI cable was used. The SCSI cable in question is rather beat-up and the drive itself is somewhat questionable (it's in a 20SC case but the internals are something I threw together myself two years ago; the drive already has a few SCSI ID issues due to the lack of a usable switch for the number). I don't think I'll use that drive enclosure again in its current form on any machine and will likely play around with its internals whenever I get a free moment.
