CSIRAC Emulator
Australia's first computer, runnable on a web page with its original tapes
A working 1949 machine and the first programming language written in Australia are now one link away, which turns a piece of computing history into something you can poke at.
Grahame Bowland has ported John W. Spencer's Turbo Pascal program CSIRACEM to a Vite, React and TypeScript web app, with Spencer's permission and original sources kept alongside. You can load the surviving paper-tape programs, step the machine, and write and run Interprogram, the high-level language developed for CSIRAC in Melbourne around 1960. The repository also collects the programming and Interprogram manuals as PDFs for anyone who wants to go further. It is free, needs no install or account, and the source is AGPL-3.0 on GitHub. It reached Hacker News on 9 September to a quiet reception.
