Well, I've got a phone call scheduled for later tonight with Zonn, so we'll
see if he'd be into me redesigning / reprogramming the ZVG to be USB.
Buying an old computer to work with it just seems like putting a bandaid on
the problem. I don't have a lot of room here in NYC, and the room that I do
have is already occupied by several monitors and synthesizers and guitars,
so there's not a lot of space left for a ancient tower PC that has only one
purpose. Or rather, there is space, but it's kind of reserved for walking
room.
