was to be a seminal influence on hacker culture at MIT in the late 1950s prior to the introduction of the PDP-1. The BMEWS DIP computer, NORAD Combat Operations Center (COC), Colorado Springs, Colo., beginning in 1960. Tape code was essentially base-32. Electrodata 205. ElectroData was purchased by the Burroughs Corporation, and many later Burroughs machines also used Flexowriters The Librascope LGP-30 and LGP-21 The Packard Bell PB 250 The SEA CAB 500 The ALWAC III-E The English Electric KDF9. The Whirlwind I deployment in 1955 is notable as it seems to have been the first time that a typewriter-like input device was directly connected to a general-purpose electronic computer, becoming directly ancestral to today's computer keyboards. Offline punch and printer Flexowriters could also be used as offline punches and printers. Programmers would type their programs on Flexowriters, which would punch the program onto paper tape. The tapes could then be loaded into computers to run the programs. Computers could then use their own punches to make paper tapes that could be used by the Flexowriters to print output. Among the computers which commonly used Flexowriters for this task was the DEC PDP-1. Machine tools The ability to support diverse encodings meant that adapting Flexowriters to generate the paper tapes used to drive CNC machine tool equipment was a relatively simple affair, and many Flexowriters found homes in machine shops into the 1970s, when magnetic media displaced paper tape in the industry. Unit record and early computing Friden manufactured equipment which could connect their calculators to Flexowriters, printing output and performing unit record tasks such as form letters for bills, and eventually manufactured their own computers to further enhance these capabilities. These variants were sold as the Friden Computyper. Computypers were electromechanical; they had no electronics, at least in their earlier models. The calculator mechanism, inside a desk-like enclosure, was much like a Friden model STW desktop calculator, except that it had electrical input (via solenoids) and output (low-torque rotary switches on the dial shafts) . Commercial printing A product known as the Justowriter (or Just-O-Writer) was developed for the printing industry. It allowed typists to produce justified text for use in typesetting. This worked by having the user type the document on a Recording unit, which placed extra codes for spacing on the paper tape. The tape was placed into a second specially adapted Flexowriter which had two paper
