You know, someone made a copy of Windows 1.03 that you can put on a 3.5" floppy and boot on modern PCs for a look. I have a copy... Interestingly even the USER.DLL GDI.DLL etc seem to be implemented as overlays.
Kept me bemused for a short time ;-)
It is still around. A quick Google should locate it if you want it, although I'm pretty sure I still have a copy.
