It cannot check a file system larger than 2GB. 'When the Apple Workgroup Server 95 starts up, the fsck command is run from the A/UX Startup application. Try to keep your specs within reason though: Apple Support Doc ID9129 I have a Quadra 610 that runs quite nicely with an 810MB hard drive and 16MB of RAM, and a Quadra 800 that smokes with 2GB and 64MB. If you have the manuals for A/UX 1.X please contact me.Ī complete installation of A/UX 3.0.1 will require about 80MB of hard drive space (160MB recommended), and 8MB of RAM (16MB recommended). The IIcx may be able to run A/UX 1.0.1 - I can't find documentation to confirm or deny.

The Mac SE/30 will run A/UX 1.1, but it was not officially supported. The 'wicked fast' Mac IIfx would probably be okay, but I would recommend a 68040-based Mac for A/UX 3.1.1. Note: While the Mac II, IIx, IIcx, IIci, IIsi, and the SE/30, will run A/UX 3.1.1, performance will be less than spectacular. Before installing on one of these models, you will need to replace the LC040 with a full 68040 processor. The Centris 610/650, and some low-end Quadra 610's shipped with a 68LC040 processor (no FPU). The PMMU is integrated in all but the original Mac II. Note that A/UX requires a PMMU (Programmed Memory Management Unit) and an FPU (Floating Point Unit). The chart below shows all fifteen supported Macintosh models, and what versions of A/UX they will run - Green indicates a supported combination. A/UX bypasses the Macintosh Toolbox, and communicates directly with the hardware, so changing the gestalt (system ID code) will not let you install on an unsupported model.Īs of 2021 there are two emulator capable of running A/UX: Shoebill - which runs A/UX 0.7 through 3.1.1 Qemu - emulating Quadra 800, which runs 3.1 through 3.1.1

Similarly, none of the PowerBooks, LC's, or AV Macs are supported. If you're trying to install on a PowerPC, stop now. A/UX was designed for the legacy Macintosh (those based on the Motorola 680x0 line of processors), and was never ported to the PowerPC.
