Do you mean gas discharge (like the Sumlock Compucorp
on my desk with a
Panaplex display), or vacuum fluorescent (the green displays used on a
number of 1970's hand-held calculators)?
Probably vacuum fluorescent.
Gas-discharge would be more like Nixies, right?
Speaking of, kinda related, anybody know where I can get one of the
21" DEC orange gas plasma displays? I forget the model number right
now, but I've been looking for one of them for quite a while...
