The IBM 608 Transistor Calculator, a plugboard-programmable unit, was the first IBM product to use transistor circuits without any vacuum tubes and is believed to be the world's first all-transistorized calculator to be manufactured for the commercial market.

Mar 28, 2021 · Developed in the mid-1950s as part of IBM's Modular Accounting Calculator (MAC) program, the IBM 608 is a transistorized version of the 604 that "combines the newest advances in electronics to perform the mathematical operations of addition, subtraction, multiplication, and division.

Mar 25, 2025 · The IBM 608 was designed to perform complex calculations quickly and accurately, with a decimal limit of 40 nine-digit numbers. It was highly versatile and could perform various mathematical operations, including addition, subtraction, multiplication, and division.

Mar 22, 2025 · In April 1955 IBM announced the development of the IBM 608 calculator, the first all solid-state (fully transistorized) computer commercially marketed. The machine was first shipped to customers in December 1957.

The IBM 608 calculator was the first completely transistorized computer available for commercial installation. Announced in April 1955, the 608 began the transition of IBM's line of small and intermediate electronic calculators from vacuum tube to transistor operation.

In April 1955 IBM announced the IBM 608 transistor calculator, which they claim was "the first all-solid-state computing machine commercially marketed" [7] and "the first completely transistorized computer available for commercial installation", [8] and which may have been demonstrated in October 1954, before the CADET.

Oct 7, 2018 · IBM 608 calculator. 1954 – IBM created the first calculating machine to use solid-state transistors. This was the first nail in the coffin for vacuum tubes.

Oct 7, 2024 · IBM researchers modify an existing model 604 vacuum tube calculator to use transistors. This experiment didn’t shrink the desk-sized machine nor make it any faster, but it did use only 5% of the power the vacuum tube-based design did.

Developed in the mid-1950s as part of IBM's Modular Accounting Calculator (MAC) program, the IBM 608 is a transistorized version of the 604 that "combines the newest advances in electronics to perform the mathematical operations of addition, subtraction, multiplication, and division.
