Still, for the 2/120 I have two video options:
1) I have some sort of Extron ECL video converter in the garage, I'll take

2) Failing that, I can switch the framebuffer to TTL and rig up my own
I have plenty of (color) monitors that will handle the resolution and
timings in question- and I'm quite pleased to have found the requisite
matching input devices. :)
Perhaps the correct monitor will turn up eventually...
