There was a mention of " real radios glow in the dark" which brought
back memories of the first logic equipment that I worked on back in the
60s. It didn't glow in the dark since the little pencil tubes didn't
put out a lot of light like the larger ones. The equipment was all
digital and all tube based. The later generations were solid state
(potted logic ice cube modules) and discrete components, no ICs then.
They weren't computers that you could program but specialized
processors....
I still have some of those "glow in the dark radios" and test equipment.
