You can try your hand at installing other disk images if you have some but those are not guaranteed to work. The emulator is fully functional, allowing you to run some old Mac OS 8 software and games, some of which are even pre-installed (legally, hopefully). The journey down memory lane doesn’t end at the hardware, of course. That makes Apple Silicon the company’s third transition to a new computer architecture (Motorola CISC to PowerPC RISC, PowerPC RISC to x86, x86 to ARM). It was one of the two last Motorola-based computers before Apple switched to the PowerPC. Under the hood, it emulates a Macintosh Quadra 900 from 1991, a computer that ran on a Motorola CPU back when Motorola was actually an industry giant. Macintosh.js probably falls somewhere in between. Javascript itself has been used to power and build all sorts of experiments, including some that make no sense other than as bragging rights or, of course, entertainment. Slack developer Felix Rieseberg has shown off his programming chops at using Electron, the Javascript application framework that Slack itself uses to build its popular communication tool.
