a powerpc xserve (running OSX server)
a sparc box (on solaris)
an alpha box (on either VMS or Digital Unix)
a pa-risc box (hp-ux)
a modern power box (Rocky or AIX)
an itanium box (running either VMS or NT depending on what the alpha is running)
a pi cluster (plan 9)
and a commodity x86 server (running OpenBSD, FreeBSD, Debian, Hurd, Redox, Serenity, reactos, and AROS).
and make a MOAP (mother of all pubnixes). if anyone has any hardware they'd like to donate, get in contact :)
Unless it's a super fun hobby for you, I wouldn't plan on this being very fun after the first dozen random crashes.
> I do. But I do not need just any Unix shell account, I need old and weird ones! I develop and maintain a portable utility (rlwrap) that is aimed at users of older software
Thank you, personally. I've used it in several contexts not just old systems, for example rlwrap is recommended with Clojure (okay, perhaps that's a comparatively small audience).
Maybe in the modern age someone could make a "polarhome in a box" that offers a similar gamut of systems, but via preconfigured emulators that you can simply download and run.
Until now, I have used qemu (or rather qemu-system-aarch6 in combination with binfmt-misc) on Linux to emulate e.g a Raspberry pi running on arm64. This works very well, but for e.g. Solaris or HP-UX there is the extra hurdle of getting hold of bootable media that will not freak out in the unfamiliar surroundings of a qemu virtual machine.
I have never tried, and it is possible that I overestimate the difficulty...
