The IBM 603 Electronic Multiplier was the first mass-produced commercial electronic calculating device; it used full-size vacuum tubes to perform multiplication and addition. [1] (The earlier IBM 601 and released in the same year IBM 602 used relay logic.) The IBM 603 was adapted as the arithmetic unit in the IBM Selective Sequence Electronic ...

In 1946, it began an important transition away from mechanical computing with the debut of its IBM 603 Electronic Multiplier. The 603 was the world’s first mass-produced electronic calculator.

IBM 603（IBM 603 Electronic Multiplier）是 IBM 旗下的一款电子产品，推出时间是1946年9月。 在电子计算机出现 之前，IBM的主要业务领域是机械式数据处理，致力于生产能够采用齿轮、嵌齿和继电器以无数种方式进行计算、制表和测量的机器。 IBM 603电子乘法器（IBM 603 Electronic Multiplier）在1946年9月推出，是从机械向电子计算过渡过程中的一个里程碑。 [1-3] 603 是世界上第一个批量生产的电子计算器。 它的计算单元中使用了300个真空管，与向计算器中传送数字 …

603 是世界上第一个批量生产的电子计算器。 它的计算单元中使用了 300个 真空管，与向计算器中传送数字并通过纸卡返回结果的 IBM 520 型读孔单元连接。 其计算单元计算两个 6位数乘积的速度比当时的其它计算机器快 10倍。 系统每小时可以执行多达 6000次计算。 据 IBM 603 官方手册指出，每个乘法运算在 0.027秒内完成。 手册指出：“电子乘法器利用最新开发的电子电路以极高速度执行计算。 因此，对于计算产品，繁重而且通常低速的过程被简化为自动的高速过程。 603 …

2021年3月28日 · The IBM Type 603 Electronic Multiplier, 1946, the first electronic calculator ever placed in production . A "box of 300 vacuum tubes" [ 74 ], all it did was multiply two numbers that were punched on a card, punching the result on the …

2025年2月19日 · In 1946 IBM commercialized the Vacumm Tube Multiplier, calling it the IBM 603 electronic multiplier. This special purpose device was the first electronic calculator ever placed into production, and altogether 100 603s were manufactured. The 603 consisted of two boxes: the Type 603 calculating unit and Type 520 punch-read unit.

Read a short article on the 603 digital multiplier from the IBM archive. Learn more about the electronic multiplier by visiting Columbia’s Computing History’s page on the 603. This resource includes general information on the machine, text of Thomas J. Watson discussing the 603, and several images of the machine.

The IBM 603 Electronic Multiplier was the first mass-produced commercial electronic calculating device; it used full-size vacuum tubes to perform multiplication and addition. The IBM 603 was adapted as the arithmetic unit in the IBM Selective Sequence Electronic Calculator.

Announced on September 27, 1946, the IBM 603 Electronic Multiplier was the first electronic calculator ever placed into production. It consisted of two boxes: the Type 603 calculating unit and Type 520 punch-read unit. This machine provided multiplication speeds several magnitudes higher than earlier electromechanical devices.

IBM also used PowerPC 603e processors in the IBM ThinkPad 800 series. In certain digital oscilloscope series, LeCroy used the PowerPC 603e as the main processor. [ 20 ] [ 21 ] The 603e processors also power all 66 satellites in the Iridium satellite phone fleet.
