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.
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.
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.
It started as a shower thought on how to rank arbitrary items and ended as a janky web app written by a backend luddite who refuses to use frameworks. So here it is, a better tier list... Or not, it sort of sucks in practice.
