Your first FPS was...

[LePresident]

Welcome to the club !
Same for me, except I started to play Wolfenstein on my 286/12 with 640 Kb RAM...
I only had my 386/40 4Mb RAM one year later, with Doom...

Damn, the university 486s was a pure pleasure, even the 486/25

Also, I remember one of our teacher in 1993, who explained us 200 MHz was impossible to reach, due to some physical limitations
Genius !

Also also, I remember one of my friend's father bought a 486/66 in 1994, and we were amazed to discover a CPU with a cooler and a fan.
Before that, 286, 386 and even 486/40 CPUs were stock, no cooler, no fan, no thermal paste.
It was easy to see what CPU was in a machine, one just had to open it and look what was written on the CPU

If you remember kind of stuff like that, you're not ancient, you just have a lot more XP than kiddos
