It was a throwaway IBM PC I'd gotten back around 1999, none of which were needed anymore at the place(s) my relatives worked at which is where they came from. They weren't fast at all compared to the hardware of that time, and certainly not today...if you had one of these computers or anything else from the 80s/early 90s, you'd know that anything from that era would move at a snail's pace compared to even the smallest of today's devices. I'm guessing that place was going through an upgrade of sorts and switching over to newer equipment, or maybe they just had to get rid of some equipment for whatever reason, I don't know exactly. I'm not sure of the specifics, but it looked similar to this one:
16 colors max, no mouse and no fancy GUI, but you had what's IMO one of the finest keyboards ever made. I do remember that the one I had booted up directly to what's called GW-BASIC (a variant of the BASIC programming language), and try as I did none of the 5.25" floppy disks I had seemed to work. Maybe I wasn't doing something right with the disks or maybe that's just the way it was, I don't know...I was pretty young (13 years old) when I had it and really didn't know what I was doing at first.
Having it was pretty significant for another reason though, as that's the time when I started taking to coding. Again, really didn't know what I was doing - it was all Greek to me at first - but I decided to hack it anyways and flip through the GW-BASIC manual that came with it to figure out how to write programs. I got better at it eventually, nothing spectacular or game changing, but an interest for learning how to write code. All of it on my own too, self-taught - the rest of my family would have been scratching their heads trying to figure out how to operate the damn thing in the first place.
I moved on to QBASIC on a Windows desktop with a hell of a lot more horsepower not long after that. After learning QBASIC, I tried my hand at other languages like C/C++, Visual Basic and Pascal. Had I not done any of this I don't think I'd know a single lick about coding today, much less even be interested in it.
