Web-based IBM 1620 emulator and IPL-V from 1963

A web-based emulator recreates the IBM 1620 Model-2 computer, a 1960s decimal computer system designed for scientific and engineering applications of which approximately 2,000 units were produced between 1959 and 1970. The Model 2, released in 1962, featured faster memory cycle times and hardware-optimized arithmetic compared to the original Model 1, with optional capabilities including hardware division, index registers, and binary operations.
