> Windows 3.1 had no memory protection at all All of the below is... IIRC Win16, even in protected mode, in general didn't unless you opted out of the shared VDM. This was to preserve compatibility with how non-protected mode code worked. That said 32bit code or code that specifically marked itself as protected mode got it's own memory space. > I just couldn't wrap my head around the idea that I'm multitasking operating system could exist without memory protection NGL... I was shocked when I found out that MacOS before 10... really didn't have much protections at all. |
