Only when it is running UNIX is it a workstation. Amiga DOS does not qualify as a workstation OS.

Plain ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ How?????? >BSD can run in 640K on an 80386. That's the latest BSD, by the way. The problem When my machine boots without the DP server it has 12Meg of real memory free. It is a 12Meg sytem. I can use it in single user mode. With DP running it still has enough free mem. to run lots of stuff and not swap continuously. >with the NeXT is they took an intermediate port of a research O/S (Mach) and >used it.

Why? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Where do you get your numbers from. I have my swap space low water mark set to 10M and unless I use lots of apps my 12Meg system doesn't swap. >It's got two operating systems in there: Mach *plus* most of BSD. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You should learn something about the NeXT and Mach. Mach is a kernal that runs under BSD. The NeXT uses UNIX with a Mach kernal. >-- >Peter da Silva. `-_-' >. -- /* -The opinions expressed are my own, not my employers. */ /* For I can only express my own opinions. */ /* */ /* Kent L.
