Most Mac users today never experienced the fun and frustration of using the pre-2001 Mac OS 8 operating system on a Motorola 680X0 or PowerPC-based Mac. Thanks to developer Felix Rieseberg, a 68k Mac emulator called Basilisk II by Christian Bauer and others, and a compiler called Emscripten by James Friend, you can now run a virtual 1991 Mac Quadra 900 on your current Mac.
Rieseberg starts his Github description of what he calls simply “Macintosh.js” (download link) on a jovial note: “This is Mac OS 8, running in an Electron app pretending to be a 1991 Macintosh Quadra. Yes, it’s the full thing. I’m sorry.”
What surprised me is how fast this emulated Mac is; much faster than any actual Mac of the time. Under the multicolor Apple icon are a bunch of the common features of Mac OS 8 including the Control Panels, Jigsaw Puzzle, and even the 1991 version of Stickies!
Macintosh..js is a fun trip down memory lane, and I expect that I’ll keep it on my Mac for a long time…just to appreciate how good our current Macs are!
