The high-speed photoelectric paper tape reader ( 250 hexadecimal digits per second on five-channel paper tape for the PR-1; 400 characters from 5-8 channel tape for the PR-2 ) read programs ( and occasionally saved data ) from tapes that were often mounted in cartridges for easy loading and unloading.
