Back in the era's tail end (as a kid) I moved from Commodore 64 to the famed DOS+Win3x combo. Marked the finale for me with non-x86 computing. My interest in them has never recovered.
Most of those numerous other systems I got to briefly play around on were little if any appeal. Apple II was OK if I recall. Not much Amiga use. Don't remember if I actually ended up trying Atari ST, Commodore 16, Vic-20, or whatever else that former collector owned. There was an Apple Lisa for some reason they couldn't use.
Sure sometimes I'll find an old computer to try reselling, but I don't have the heart in even that idea to take it seriously. So I tend to lose money on such feeble attempts..
