The 80286 had sufficient memory management hardware for full Unix. What it did not have was sufficient memory management hardware for reasonable demand paging, but it was fine for swapping systems.
Wasn’t 16-bit OS/2 demand paged on the 286?
- AshamedCaptain 3y agoNot "paging" per se (since the 286 doesn't have that, by definition), but demand loading/unloading of code is possible on a 8086, and even the original Windows does it (see https://devblogs.microsoft.com/oldnewthing/20110316-00/?p=11203 https://devblogs.microsoft.com/oldnewthing/20110316-00/?p=11... ).
