>OS3.9 lists 6MB of Fast RAM in its requirements... Still a lot less, but 16 times less, not 50...
I know, but 6Mb isn't necessary, it will indeed boot on a 2Mb system.
Maybe but what you can do today with only 2 MB ...
From time to time I continue to use OS 3.9 under emulation and hey to use it decently i need 16/32 MB at least ...
As other say OS4 is far advanced compared to the old OS 3.9 so there is a reason to require 64 or 96 MB (just for the new memory system and tons of the new features, graphics and so on)
Also how mutch cost memory today ?
