Subject: seven segment display history
Does anyone know when seven segment displays first appeared on the scene?
Presumably the first ones were VF, and LED came later?
Probably incandescent side lite first, maybe electroluminescent,
incandescent Numitron?
(I was just looking at a museum's mock-up of the Apollo mission control
console, and the fake readout is made to look like a 7-seg display; I'm just
surprised that the digital readouts weren't all Nixie-based back then)
cheers
