By placing a color gel in front of it, you could select just the instantaneous blue-green signal, or the partially-summed yellowish one. The later was used when the Germans would broadcast jitter signals out-of-sync to cause noise, because it shifted around so much it didn't appear on the afterglow. | |

| Oct 9, 2018 at 10:43 | comment | added | Geo... | I worked on Radar systems, and I didn't know about the Px rating system (or perhaps I forgot long ago). But it makes me wonder what the P rating would be for an original Atari Asteroids cabinet. Those vector displays had a beautiful 'afterglow' persistence... | |
