New VFD Arrived

My EMAX POS pole displayed arrived the other day and the VFD is huge! The spec sheet says it is 15 x 4 cm - much larger than I imagined. It is a parallel Samsung VFD, which connects to a board that translates the RS232 and AEDEX protocol used in some cash registers. There is not serial interface on the VFD unfortunately.

The protocol was very simple to figure out, and after some cable modifications, I got it running using Zterm. Now I am going to start trying to get the LCD Kit to work directly on the VFD, without the other board. I'll keep everyone posted.
