2019 UPDATE: I've actually taken another look into A/UX both on an SE/30 and now permanently on a Quadra 700. The SE/30 without an accelerator runs A/UX 3.x a little too slow for my liking. The Quadra 700 runs A/UX 3.1.1 at an acceptable speed. My configuration is an 8GB SCSI2SD for storage (2GB root/usr, 2GB spare slice, 40MB for the standard MacPartition, 2GB secondary HFS volume for Mac purposes, 128MB swap, the rest unpartitioned for now), 20MB RAM though upgrading to 68MB (64 via SIMMs, 4 onboard), extra 512K VRAM added. Will be working on a newbie guide for A/UX (see link at the bottom).
UPDATE: I purchased a Centris 610 motherboard on eBay to replace my non-ethernet board and I noticed it had a full 68040 33mhz chip (though runs at 20). I put together a complete system with 52mb RAM, 250mb HD, 230mb HD, and an Apple 14" monitor and installed A/UX with no trouble. I also had a PPC 601 upgrade card but I removed it because it generates quite a bit of heat even when not in use. Read the "how to install" section for info on 68040 systems and A/UX. I will also add new screenshots soon.
For this experiment, I went with a Macintosh IIci (25mhz 68030) with 20mb RAM, a 250mb SCSI HD, and an external Apple CD 600 (2x). The IIci also has a cache card. For video, I use an Apple 13" RGB display on the onboard port.

to install A/UX
this document will describe the process of installing Apple's A/UX operating system. to do this, you will need a computer with a cd-recorder, the cdrecord application (or toast for macs), and a 68k macintosh equipped with at least 16mb ram, an 80mb hd, and a cdrom.
TO BURN THE CD:
In Windows - download the gzipped cd image from higher intellect (hotline://preterhuman.net). download cdrtools from somewhere. extract the cd image to the cdrtools folder. open a DOS window and run "cdrecord.exe --scanbus". find the three numbers representing your cd burner. insert a blank cd into the recorder and run "cdrecord.exe dev=(insert three numbers) imagename". an example for my system is "cdrecord.exe dev=1,0,0 AUX_30~1.IMA"
In MacOS - download and extract the cd image. launch toast and burn the cd image.
In Linux - use the cdrecord command syntax as seen in the windows instructions (untested as i have never burned a cd in linux)
TO BOOT A/UX:
download the install floppy image from higher intellect and either rawrite it (in windows), dd it (in linux), or diskcopy it (in macos) to a 1.44mb floppy. now turn on your mac, insert the boot floppy and the A/UX cd. it should boot into the installer script. NOTE FOR 68040 USERS: you will need a system enabler file on the boot disk. If you use a Quadra or Centris that uses the System Enabler 040 then your system should work. Systems that use the 065 enabler might not (I put a full 68040 in an LC 475 and A/UX wouldn't work). Enablers are available at the Apple FTP site.
TO INSTALL A/UX:
use the buttons to select which drive to install to. then customize the to-be installed software list to match your needs. after you are done, the installation process begins. after the install you should have a bootable copy of A/UX on your hd. NOTE FOR 68040 USERS: if you successfully booted to the install program then your system should work fine, as it has already loaded the A/UX kernel for installation. If your screen goes blank during the A/UX loading phase and stops responding, your machine is incompatible.
I am currently writing a complete newbie guide to building an A/UX machine and getting standard tools working like gcc, httpd, and TCP/IP networking.
