There was(is) a 640Kb limit in the DOS/Windows 3 'native addressing' structure/management mode same sort of thing as the current limit on usable memory within XP of 3Mb and 4Gb Any memory above that limit had to be addressed as extended memory, using additional 'drivers' so originally it was used for ramdisk, then as 'highmem' for holding some modules Then utilities such as Sidekick Then used by some modules of office type packages etc. JimB ----- Original Message ----- From: "Hugh Gundersen" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, January 18, 2006 4:53 PM Subject: Re: Brief History of IBM PCs (WAS RE: Mobo caps - again!) <<Hack>> >As far as I remember the 80186 was produced as an embeded processor and >was an 8086 in a square package and not a DIL package.
