Some systems also had expansion cards with an x86 processor on them. A more recent example would be Sun's SunPC and SunPCI cards -- you plugged these in a SBus or PCI slot, and ran x86 code on a real x86 processor. IIRC that's actually what the AT&T Unix PC did, too, but I'm not sure (I never owned one).
- sanxiyn 2y agoSee "DOS-73 Technical Reference" on the linked page for details. Yes, DOS-73 expansion cards had 8086 CPUs.
- mschaef 2y agoSun also briefly made a 386 based workstation. It didn't do well, but it could run DOS via V86 in a window on an otherwise Sun desktop. https://en.wikipedia.org/wiki/Sun386i https://en.wikipedia.org/wiki/Sun386i
