The IBM 604 Electronic Calculating Punch was the world's first mass-produced electronic calculator along with its predecessor the IBM 603. [1] It was an electronic unit record machine that could perform multiple calculations, including division.

The 604 performed addition, subtraction, multiplication, and division hundreds of times faster than any of IBM's earlier electromechanical machines, and was the first IBM product to use modular vacuum-tube based pluggable units, later used in IBM's NORC and 701 computers. The 604 was programmable via plugboard and could execute a program of up ...

2023年3月23日 · IBM 604是IBM开发的一种基于打孔卡的电子管计算机，是第一台使用可拔插模块化电子管的计算机，这个设计降低了维护和生产成本。 电子管的顶部有把手，可以方便操作人员抽出电子管，计算模块包含大约2000个这样的电子管，它们是由几种不同型号的可拔插模块组成。 许多电路被安装在电子管尾部中，使得电子管可以布置得更为紧凑。 IBM 604工作频率为50kHz，程序编写是通过电路板实现的。 最初可以编写40道步骤的程序，升级后可支持60步 …

In April, 1997, the Computer Museum has acquired its first (and only) electron tube-based digital machine, the IBM 604 Electronic Calculating Punch. In fact we have only the 604 arithmetic unit (the larger cabinet in the picture to the left), without the card reader/punch. The machine is not in operational condition.

2019年5月10日 · IBM604，是IBM开发的一种基于打孔卡的 电子管计算机，1948年推向市场。 它的主体部分重量为640公斤，长、宽2米，高1米，和同时代计算机相比算是迷你了。 输入数据需要同521型打孔/读卡器配合，读卡器每小时可以处理9000张卡片。 计算时还要配合几台941型外部存储设备。 在1948年到1958年期间，IBM生产了5600台这种机器，产量很高因此价格比较便宜，一套604+521的租金为645美元一个月，它的主要销售对象是工商业部门。 这个价格相对来说比 …

In the 604, IBM had to face for the first time a number of problems whose solutions would be important to the computer industry as a whole: the problems of manufacturing, testing, maintaining, and repairing an electronic machine to be produced by the thousands and installed wherever punched-card machines were used for calculating. Ralph Palmer ...

THE IBM Electronic Calculating Punch, Type 604, uses electronic methods for performing all basic types of calculations. Factors are read from IBM cards, the calculations are made by an electronic calculating unit in a fraction of a second, and …

This is a small wired plugboard from an IBM 604 multiplying punch. After World War II, IBM engineers built the one-of-a-kind Selective Sequence Electronic Calculator, which used vacuum tubes. It also built and sold in large numbers a new form of calculator called the IBM 604, its first electronic product.

The IBM 604, introduced in 1948, was IBM's second commercial electronic calculator and introduced pluggable modules for easier service. It could add, subtract, multiply and divide numbers from punched cards, with up to 40 program steps repeated for each card.

The IBM 604 Electric Calculating Punch is the first use of extreme parallelism: to perform multiplications and divisions more rapidly in decimal from punched cards, the 604 used an array of multi tubes, 64x64x3 and 16x2, to perform the multiplication of two 8 digit numbers and accumulate the results in 3 machine cycles, and another 2 machine ...
