The '''IBM 700 series''' was [[International Business Machines|IBM]]'s first generation of computers. They all used [[vacuum tube]]s for the [[logic]]; initial models used [[Williams tube]] electrostatic [[main memory]], but all later models switched to [[core memory]].

At this point in time, computers for scientific and business computing used separate [[instruction set]]s, so there were two independent lines of models:
