Truth: DOS has been multitasking since the early 1980s.
So… synopsis is most versions of DOS do not do multitasking, but some do and the rest can with special add-ons.
Windows was just another “special add-on” too really until NT.
Still, interesting. Wish there were more details. I’m curious how Wendin DOS and the other native multitasking ones worked though. Must’ve been preemptive multitasking since DOS programs wouldn’t have been able to do cooperative multitasking.
Sure, it’s like how you could get GEOS for the Commodore 64, or even how you can run Linux either in console mode or with various display systems and WM/DEs. DOS was the real OS and windows merely a graphical shell and some other stuff.
Cool read! I it seems topview really was the groundwork for windows.
