Sounds like the TRS-80 Screen Printer. A roll of aluminized paper was bent into an arc around a spinning drum with high-voltage wipers. Voltage pulses on the wipers would burn away the aluminum, revealing the dark background paper. Very fast, very strange.
- TedDoesntTalk 3y agoLooked it up: http://www.trs-80.org/trs-80-screen-printer/ http://www.trs-80.org/trs-80-screen-printer/ Weird. 4 inches wide. Printed the contents of the screen and nothing else. Connected directly to the bus by an edge connector (no card or serial or parallel connection).
