In the 1950's, the Electrodata corportation of Pasadena California developed a general purpose business computer.
The B100/200/300 systems are compact, high-speed, solid-state computers that use common components in several problem-oriented equipment configurations. They are capable of handling a wide variety of data processing application media such as punch cards, paper tapes, magnetic tapes and MICR documents. Each system incorporates its own associated input and output units, thus providing a greater throughput capability.
The B100 Series was available in three basic model or reference designations, the B 160, B 170 and B 180.
The B 160 is designed for punched card processing. It is capable of reading 475 cards-per-minute, punching 300 cards-per-minute, and printing 475 lines-per-minute. This system can combine in a single run collating, calculating, summarizing, summary punching, and printing operations which presently require multiple runs in conventional tabulating equipment. The components that make up a typical B 160 system are:
The B 170 system is designed to handle as input media MICR-encoded documents, punched cards and magnetic tape. As a financial institution system, it features the processing of MICR checks and deposits at speeds of up to 1200 items-per-minute. As output media, the sytsem prepares magnetic tape, punched cards and is unique in that it automatically produces up to six complete detail and master listings which show the identity, amount and disproof, transit and other operations. As a general-purpose system, it includes all punched cards and line printing capabilities of the B 160 system along with magnetic tape processing. The components that are used with the B 170 system are:
