Well, there weren't too many viable options going back to 1982, so inquiring minds want to know; if you didn't use Microsoft or Apple. . . and LINUX was only started in 1991 and really wasn't viable for years. . . what did you use? Commodore Amiga? Atari St series? Timex? UNIX? On a home computer? What?
Nothing. I had no need for any form computing back then. And, for me, Linux -- the same OS that Jim and John Robinson chose for Free Republic -- has been viable since it first came out in 1991. I used the Texas A&M distribution and to this day, it serves as the basis of what I use today since I build everything myself, the hardware, the kernel and userland.
I wish not to antagonize you but I found it pretty presumptuous that your initial reaction was to conclude that not using Apple implies an affinity for Microsoft. And yes, there are likely sodomites upstream in the Linux world as well as the downright bizarre (see Richard Stallman). The difference is that unlike Gates, Ballmer and Cook, not a penny flows from my pocket to support their agendas. Granted, I did pay postage to get the Linux floppies from Texas A&M more than 20 years ago. As far as I can recall, that's been my sole outlay for that platform.
