It ended up being a Rev 4.X board inside (a sticker on the board says 4.3, the graphics on the board say 4.1)
That'll be a 4.3, then.
The floppy drive is a bit borked, but works.
I got 2 old 2000s not too long ago, and both their floppy drives are dead. Or so I thought. From what I've read of similar accounts here, they might just be hideously, hideously dirty (the kind of dirty that requires full dis-assembly to clean). I haven't yet gotten around to attempting a repair. Seems to be a common issue with those kinds of drives.
Anyway, enjoy the machine! It's at a great starting point for some light productivity.
