Whatever model Classic Mac that supported the Apple ][e expansion card, Apple DOS expansion card, and Apple Unix install (getting you System 7? 8?, DOS, original Apple, and a commercial Unix) has got to be up there at least for the novelty for me.

Pretty sure there wasn’t one single model that did all this. The IIe card was for the LC PDS, but the DOS card was Nubus.

A/UX didn’t run on the original LC (68020, no MMU) but it may have worked on later LC series machines.

Edit. LC 630 DOS Compatible wasn’t Nubus, but it was a different PDS type than the original LC

I thought there was a Mac Performa or Quadra (like 2 or 3 very specific models only) that supported both Apple DOS and ][e cards.

And I get that the Apple DOS and Apple U/X performance on this machine might not be very good. Early 90’s computers and needing to be wrangled to even support normal, supported operations and configurations wasn’t uncommon.

I don't think so.

Apple never made a x86 DOS card for the LC PDS. Maybe a third party like OrangePC did, but I can't find a definitive confirmation online.

The only Apple II card was the Apple IIe card (LC PDS). All the machines with a LC PDS had only a single slot, so even if there was a DOS card you wouldn't have been able to use it and the IIe card simultaneously.

According to this thread, A/UX never supported any LC model due to significant hardware differences from the supported IIs and Quadras: https://68kmla.org/bb/threads/is-there-a-known-understood-te...
