Operating Systems

After seeing a poll on SlashDot for the number of operating systems you have worked with for at least an hour, I started thinking about my answer to that question.

My first guess would be something like 6-8. After thinking a little bit more, I came to the following list:

  • AIX
  • Apollo Domain
  • BeOS
  • Commodore 64 OS
  • DR-DOS
  • FreeBSD
  • HP-UX
  • Irix
  • iOS
  • Linux (HAL91, Mandrake, muLinux, RedHat, Slackware, SUSe)
  • Mac System 5/6/7
  • MS-DOS
  • Netware
  • OS/2
  • PalmOS
  • SCO Unix
  • Solaris
  • Thu64
  • VMS
  • Windows 3.x
  • Windows 9x/Me
  • Windows NT/2000/XP
  • Windows CE/PocketPC

That makes 23, amazing!!!

Of course you can always discuss about the definition of an OS. I decided to group some closely relates OS’s like Windows 95, Windows 98 and Windows Me, and the different Linux distributions, but other people might consider each of them as a seperate OS. I have been thinking to group all flavours of Unix (including Linux) in one group, but than I would also have to group all flavours of Windows. Fact is that the different Unices can be very different from each other, so I left them alone.

What is your list? Have you worked with any OS that is not on my list? Just leave your list in a comment.
