Quoted from TomDK:
Question in the club:
Anybody ever heard from a proto or earlie F-14 with the additionel 4 bulbs on the display pcb CONNECTED ?!
Many machines have this display like in Millionaire ... but so far no one ever had it connected to the PDB ..
Thanks for looking
As far as I know, they never utilized these lights on f14. I was just the other day thinking about how to hook them up somehow.
