Yes, this is the case. I would guess that the LSI multiplexes the
digits without any other drivers. The DOW labels are probably treated as
segments of a 7th digit by the LSI

I've never tried to hack right to a VFD. I've only ever played with
ones that have controllers.
I take it the day of the week display is part of the flourescent, not
LEDs behind the "Sun...Sat" labels, right?

That's more or less what I'm leaning towards. I have a Matrix Orbital 20x4
VFD from Linux Central that is currently mounted behind a disk drive bay
bracket. It is easily movable.
