First
programable calc
Then there is the "first solid state electronic calc" which I think goes to
the Busicom from Japan that employed the first production run of the intel
4000 chip set: the 4001 (2048 bit ROM), 4002 (320 bit RAM), 4003 (10 bit
shift register), and the 4004 (4 bit CPU). That chip set was shipped to
Busicom in March 1971 according to Michael S. Malone's "The Microprocessor:
A Biography" ISBN 0-387-94342-0
Wang's first (or quite near their first) product was an all electronic
calculator, introduced in the late 1960s. They are big, but could be
lugged around. The best part about them is the core memory! No
microprocessors here (in fact, it may be discrete transistors - I better
open the thing up a check).
