...And really, guys. I'm almost finished! I won't get into details (new house, trip cross country coming up), I've been way too freakin' busy..

In a nutshell, the (my project) display is powered BY the Empeg (or external PSU), and accepts serial (RS-232) input. No processing is done on the Empeg side (except for what to display) - the VFD accepts straight-forward commands to draw/erase/write to it.

No software's been written for it - I tried, and just don't have the knowledge.

Me.
