I am interested also. I don't know what I would do with it yet, but I would find something...

That's the beauty of it, so far. There's not going to be any "VFD Only" components in it, other than the +5V output for power.. So, anything that uses a TTL serial format can use this to interface with the Empeg. Fun.
Although there was a link to a small product that did RS232 -> TTL conversion in a straight-cable configuration, which may work a little better.

Me.
