1. The teletypewriter machines used punched paper tape , before the invention of chadless tape. 2. There is also punched paper tape with a Fortran 2 program for a PDP-8. 3. It used vacuum tubes, a magnetic drum, and punched paper tape readers and punchers. 4. Output was to 80-column punched cards, line printer, and optionally to punched paper tape . 5. Input was from 80-column punched cards and optionally 160-column punched cards and punched paper tape . 6. Punched paper tape was the external storage medium.7. Input and output was through punched paper tape or punched cards, and printing on a line printer. 8. Some might use some fairly old technology, like punched paper tape , to specify the notes to be played. 9. Another method Space Track later had was a secure teletypewriter machine that had a pre-punched paper tape attached. 10. Due to cost constraints, many PDP-8s had punched paper tape readers as their only mass-storage I / O device.
