A web-based emulator for the IBM 1620 Model-2, a 1960s transistorized decimal computer designed for scientific and engineering applications. About 2,000 systems were produced between 1959 and 1970, featuring a two-address memory architecture and supporting software like SPS assembler and FORTRAN II. The project aims to emulate the Model 2 variant and recover historical software.
A developer created a custom assembler for CHIP-8, a simple virtual machine instruction set, implemented in C++. The post appears to be a Hacker News submission showcasing this programming project.
