Installing A/UX 1.1 like it's the 90s
A tech enthusiast successfully emulated Apple's vintage A/UX operating system using the Snow emulator. The project involved archiving rare floppy disk media and implementing specific hardware support to run the software on vintage Macintosh configurations.
Why it matters
This project preserves computing history and demonstrates the technical challenges of maintaining legacy software on modern hardware.
Recently, I have been successful in making A/UX boot and run stable on my vintage Macintosh emulator; Snow . A/UX was Apple’s version of UNIX that ran on the 68k-based series Macs. It required a Memory Management Unit to achieve process isolation; either the optional 68851 PMMU on the original 68020-based Macintosh II or the integrated MMU in the 68030- and 68040-based machines. It also required an FPU; making it only run on the higher end machines such as the Macintosh II series and later the Quadra, but the LC was out of luck. A/UX Penelope is a nice resource on A/UX compatibility info.
