The 716 was based on
IBM 407 accounting machine technology and had 120 rotary type wheels, each with 48 possible characters. It could print 150 lines per minute. It also supplied power to the
IBM 711 card reader and 721 card punch. Only 72 characters could be transferred from
IBM 7090 computer to the 716 in a single operation, but a full line could be printed at half speed. Characters were printed by sending bit patterns that corresponded to the impulses that a 407 would see when reading a punched card. A variant of the 716, the
IBM 717 was used with the
IBM 702 and
IBM 705 computers. ==See also==
