only does upper case :( some of the punctuation looks a bit wierd.

Now there's one from the vaults!
I used the 10937 as a VFD controller in a whole line of credit card
terminals.

The chip is easy to talk to, three wires IIRC, clocked serial, plus reset.
The hard part is the VFD tube. It's -30 and -10 requirements usually can be
served with a flyback switcher, but the filament is special. Many places
drive it with a winding on the switcher, but that's not optimal.  If you
drive a flip-flop from one digit strobe (anode) then use the flip-flop to
drive an H bridge, switching the filament between +7V and ground on each
end, then you have got optimal filament drive.

DONT drive the filaments with DC though. Even the ones that are designed for
it wear out much faster than the regular type.
