Operating system preferences survey

I am using openSUSE here.I have tried Ubuntu, Mint, Fedora, Slackware. But I am still preferring openSUSE.I also have Windows 8.1 (on my desktop) and Windows 7 (on a laptop), but I am not seriously using those. I never did like Windows.Edited by nwr, : No reason given.

My first computing was on an IBM 370 mainframe.My first home computer was a Heathkit -- I don't remember the model number. That was around 1979. I indulged in a IBM PC/AT when those first came out (maybe 1982). It was quite expensive at the time.For software -- mostly I used IBM 370, either MVS or VM. That Heathkit used HDOS, with a FAT12 file system. I think Heathkit bought that from the same small developer that Microsoft used for its early software. Later I went to CPM (on the Heathkit). After that it was mostly IBM 370 at work and MSDOS at home, until around 1995, when I started to play with linux -- initially slackware. I was also using a Sun Solaris system at work at that time. I joined evcforum at around the time I was moving from Sun Solaris to openSUSE (well, to SUSE 10.1, before openSUSE existed).

I don't remember the clock rate for the Heathkit. My Heathkit used the Z80 processor, which supports a superset of the 8080 instruction set. It did not have a hard drive. It used 5 1/4 floppies.I sent to recycling (or maybe just as regular landfill) long ago. It was showing its age. The foam plastic was turning to a tar-like substance. That didn't affect its function, but made it messy to use.
