IBM 701

The first computer intended for wide-scale business use. It was based on a parallel binary system using basic and simple components, with space deliberately left for future upgrades. The system stored 4096 words of 36 bits, using CRT storage, with the adjacent memory addresses spread over the screens to eliminate the read-around problem. In the end, 19 701s were installed, establishing a user base comparatively large enough to set up the organisation called SHARE, which facilitated the sharing of a set of standard assemblers, translators and sub-routines.
