Web-based IBM 1620 emulator and IPL-V from 1963
A new web-based emulator allows users to experience the IBM 1620, a scientific computer system originally released in the 1960s. The project provides a technical look at the architecture of early transistorized computers, including their unique memory-to-memory processing and lookup-table arithmetic.

Web-based emulator and operating environment for the IBM 1620 Model-2 computer system.
The IBM 1620 was a 1960s transistorized, decimal, variable field-length, magnetic-core memory computer system designed primarily as an inexpensive solution for scientific and engineering applications. There were two models, the original Model 1 released in 1959, and the object-code compatible but significantly redesigned Model 2, released in 1962. A total of about 2,000 systems were produced, roughly half each Model-1s and Model-2s. IBM supported the system until 1970.
