I can't remember if Apple themselves hosted AUX or not on their website, alongside System 6 and 7.5, or if you could get them, ahem, from other locations.

Anyways, remarkably, A/UX could run on a Macintosh LC II and III. The LC III was remarkable in that if you found the right DIMM, it wouldn't reject a 32MB SIMM RAM chip. Long story short, you could buy an Mac LC II for $10 in 2000, and install A/UX on there. The tricky thing was that Macs all used SCSI drives back then, and most macs required the SCSI drive to have a special bit flipped (in, I guess, firmware? or bootloader?) that marked it as a Mac hardware scsi drive.

A/UX was unique in that 1. it did not require a Mac specific SCSI drive and 2. utilities existed to convert any scsi drive to be marked as a "Mac hardware" scsi drive.

TL;DR ran A/UX for a couple of weeks on a $10 Macintosh LC II that I bought at a computer consignment shop in the early 2000s
