Hi!
I have installed AMIX on my A3000UX from the original tape with the A3070. It runs with the A2410 and A2065 and I have the A2232 also (but not installed). Unfortunately after installing and a little bit of configuration I do not use it very often at the moment.
It is a nice machine and there are a few users but I do not think it is used in productive environments at the moment. The last time I saw a system in professional use it was the system from Tahoe who did administration of UNIX-servers via ssh with it.
