Operating Systems > Not Quite Mainstream OSes

Non-unix OSes?

Well OS/2 is similar in someways to Windows, it was originally going to be a kind of Windows bridge, but no the OS itself operates on slightly different principles. How similar is similar? I don't believe BE is Unix based, but it certainly implements some of it's design philiosophies. I have to admit I am not a software engineer, and I don't work at that level, although I am slowly teaching myself.

However you could argue that all OSs are Unix based. It depends where you draw the line. I inferred from Lazygamers' question that he wanted OSs that behaved significantly differently or did different things. and were not UNIX or Linux in their common forms and were not the major commercial OSs either.

Calum:
if you're saying windows and OS/2 are similar then there is only one operating system in the whole world i am afraid.

many of the systems i am sure people think of as 'unix' are not in any way the same as each other. BSD is not Linux. Linux and BSD are not minix. Minix and linux are not solaris. Solaris, minix, BSD and Linux are not UNIX. None of these is AIX, none of them is any of the other myriad unices out there.

'isn't x similar to y though?' i hear you ask... well you know what? to the user all those unices are almost identical, but internally they are totally different. their similarity to each other is one of their many strengths, but many of them contain NO CODE IN COMMON. they are TOTALLY UNIQUE from the point of having parts of the system the same.

So what makes the system? the name? the GUI? the fact that the CLI is similar? there are hundreds of completely different systems out there, depending on how you look at it, or else, as was said before, there's only one.

Master of Reality:
but Bill gates was working on OS/2 with IBM and then stole the code and went off by himself with Microsoft, didnt he? So in reality isnt/wasnt there some code from OS/2 windows. Windows is a lot like OS/2 isnt it, isnt that basically what Bill was basing it off of when he started windows?

Calum:
i am sure os/2 was started so IBM would be able to have an in house operating system to run on the IBM PC when they realised microsoft were getting far too big for their boots. Remember IBM had invented what was then known as the IBM PC, and Compaq had not yet called them on it (i think), so IBM were still the leader in home computing.

HPC GUY:
the current amiga oses are based on unix/linux the old amiga stuff i believe was discontinued in the mid 90's
