Brief History of the TI-99, A

1958 - Integrated circuit invented by Jack Kilby During the summer of 1958, TI shut down for the annual two-week, company-wide mass vacation. As a new employee, Jack Kilby had not yet accrued vacation time, so he stayed on the job and began looking for a viable alternative to the micro-module program, a miniaturization method for circuits. While studying the problem, he decided the only product a semiconductor house could make cost-effectively was a semiconductor. Perhaps other circuit components should be made from the same material as the semiconductors.
