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:

{| class="wikitable"
! Scientific !! Commercial !! Low-end
|-
| [[IBM 7090]] || [[IBM 7080]] || [[IBM 7070]]
|-
| [[IBM 7094]] ||   || [[IBM 7074]]
|}

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

+but in general the instruction sets were compatible within each line, and with those of the earlier 700 series machines. All were eventually replaced by the [[IBM System/360]].
 The [[IBM 7030 Stretch]], although not part of an existing line, was effectively a 7000 series machine; much of technology used in the others was pioneered by the 7030, including the [[Standard Modular System]] cards used to build them all.
