The '''IBM 7000 series''' was [[International Business Machines|IBM]]'s second generation of computers. Instead of the [[vacuum tube]]s used in the earlier [[IBM 700 series]] for the [[logic]], all the members of the 7000 series used discrete [[transistor]]s mounted on [[Standard Modular System]] cards. [[Main memory]] remained the [[core memory]] of the earlier machines, but larger and faster.

At this point in time, computers for scientific and business computing were still using separate [[instruction set]]s, so there were still two independent lines of models; in addition, a third line, intended as a low-end business-oriented successor to the [[drum]] main memory machines ([[IBM 650]]. etc), was added:

but in general the instruction sets were compatible within each line, and with those of the earlier 700 series machines.
