Just Bought a VFD from ebay

I just bought a VFD from ebay. It is a 20x2 model, though I have seen some nice 40x2 models pop up at a decent price. It is from a point of sale display, so I don't really know exactly what I'm am getting. It was cheap though, so if you want a good price on a VFD, look for surplus POS displays. Mine was 99¢ plus shipping.

Since it is from a POS machine, it probably uses serial input, but like many of the Noritake VFDs, it might have parallel too. If so, I will try it with the parallel adapter and let everyone know my results.

Ultimately, I would like to get this working with LCDproc, and write a Growl plugin to connect with LCDproc. That way, I would not have to write any more code for formatting data for the LCD/VFD. This should open a lot of doors for people wanting to use LCDs on Mac OS X.
