Ok, so the title isn’t as catchy as “Back to the Future,” but my guess is a lot of people who are advanced Linux users have — at least — a slight interest in retrocomputing. You’d like an Altair, but not for $10,000. You can build replicas of varying fidelities, of course. You can also just emulate the machine or a similar CP/M machine in software. There are many 8080 or Z80 emulators out there, ranging from SIMH to MAME. Most of these will run on Linux or — at the least — WINE. However, depending on your goals, you should consider RunCPM. Why? It runs on many platforms, including, of course, Linux and other desktop systems. But it also will work with the Arduino, Teensy, ESP32, or STM32 processors. There is also experimental support for SAM4S and Cyclone II FPGAs.
