I'm getting close to finishing a ZVG project, but it's a software project
After banging my head against the wall looking for mobos and sound cards that support DOS in just the right way, I decided to port vectormame to windows.
Basically, I'm using the windows MAME .137 build and the DOS MAME .106 code (the last version of MAME that supported the ZVG). It's been quite a project (MAME has changed a lot over those 31 versions

, but things are looking good.
I may be jumping the gun here, but I have windows running vector games and sending data to the ZVG across the parallel port. Tonight I'm going to hook up my WG6100 and see what happens -- can't wait!
If this works, it should make it MUCH easier to set up a vector mame (sound, USB, better performance, etc.)
Wish me luck!
