"What kind of displays would you all want in a vector monitor tester?
Crosshatch only? Maybe a "plus" sign for convergence? It might be
do-able for not too much money with a PIC and a little dual-serial DAC
or something. Think it needs three outputs for color? (or just one that
you could switch from gun-to-gun? hard to do convergence that way
though).

if you want, I can send a WICO one for you to look at
