Web浏览器中的IBM 1620计算机模拟器项目

该项目开发了一个基于Web浏览器的IBM 1620 Model-2计算机系统模拟器1。IBM 1620是20世纪60年代推出的晶体管十进制计算机，主要用于科学工程应用，共生产约2000台1。Model 1于1959年发布，Model 2于1962年发布，两个型号大约各占一半1。

模拟器项目的目标是创建Model-2变体的模拟器并恢复该系统尽可能多的软件1。IBM对该系统的支持持续到1970年1。在硬件规格方面，Model 1的内存周期时间为每两位数字20微秒，Model 2改进至10微秒1。系统的基本内存大小为20,000位数字，可扩展至60,000位数字1。该项目采用MIT License许可证发布1。

A new project has created a web-based emulator of the IBM 1620 Model 2, a transistorized decimal computer system from the 1960s 1. The IBM 1620, which was introduced with Model 1 in 1959 and Model 2 in 1962, was primarily designed for scientific and engineering applications and saw approximately 2,000 units produced, split roughly evenly between the two variants 1.

The emulator initiative aims to reconstruct the Model 2 variant while recovering as much of the system's historical software as possible 1. The original IBM 1620 operated with a memory cycle time of 20 microseconds per two digits for Model 1 and 10 microseconds for Model 2, with base memory configurations of 20,000 digits expandable to 60,000 digits 1. IBM provided support for the system through 1970 1. The project is released under the MIT License 1.
