“Wheels within whiles!” or possibly “Whiles within wheels!”
summary
Built a multi-layer stack that spans 150 years of digital computing tech, running a modern laptop through five layers of emulation down to Babbage’s Difference Engine and tying together an old Mac, an IBM 1401, an Analytical Engine model and more with bits of code the uploader already had. Demonstrates concrete wins: IBM 1401 emulation strategies, an ASAP processor emulator used to retarget GCC, a few surprising bugs found and mostly working results that actually run historical programs.
