I had used a bunch of these back in the day... I purchased yhese Futaba Vacuum Flourescent displays for $4 each. I wanted a winamp display and a unique nameplate for my desk. It comes with a 10 pin connector but 5 of those get grounded 2 for +v5 and three data signals.... Using a pic18f452 to drive it. Also ported it to an pic18f1320 hex file below is for the 18f452 that works with the schematic shown. Also have code for a car warning message panel
Here is a shot of the display. It draws about 1 amp at 5V so it's not a miser but it is bright and only 5 connections to make it work.
Thought I would archive these files here…
Even made a simple VB character generator
