Hello! Egads! Years earlier I had an EMG done, it was as always inconclusive. One of the output devices used paper like that. One of the workers showed the output paper to the room lights to develop it. Now why is there a big dino with feathers on it, sleeping next to the museum building? ----- Gregg C Levine gregg.drwho8@gmail.com "This signature fought the Time Wars, time and again."

When I was at UMASS in the 70's, we had a printer on the Tektronix 4012 that had some strange paper like that. White crystals grew on the case where the paper came out - kind of strange, I wonder what the technology was?
What I am familiar with for the storage tube machines used dry silver paper. It was exposed by a line CRT in the printer then developed with heat.

They did make a electrostatic one. Never saw it in person. Did use 4610 and 4631 when they were current.
