I don't see why. I've seen early 1970s guitar amplifiers that use a
large EL strip for the control panel backlight. It's not a huge stretch
to imagine that NASA would make a display for a spaceship computer out
of them a few years previously.

Yes, I'm finding those references as well. Although it seems quite early for
electroluminescent displays too, don't know of anything else that was using
them at that time, esp. in 7-seg form. And whats up with this mention of LCD displays? I
didn't think there was
anything practical available that early, or that was going to stand up to the
rigours of space-flight - I have a calc with one of the first commercial LCDs
(1972) and it's still kind of rudimentary - slow, poor contrast, temperature
sensitive...
Doing a bit of googling on the AGC, I found that it uses
electroluminescent displays.
