I have a fondness for the intel Pentium 133 and Intel 486DX2-66.
(Though I grew up with XTs and ATs, I was not much aware of the CPUs at that time, and all I cared about was the games running on it, from Zaxxon, Lode Runner to Karateka and Pit Stop.)
I bought (actually asked to get for me, after many trials) a 286 at the wrong time - when 386SX were about to be released and my greedy self couldn't wait.
I had great nostalgic moments with the 286 with almost all the classic adventure games from Sierra and Lucasarts running on it. And simulations from Microprose and. "Gold Box" RPGs from SSI. Not to mention played Wing Commander 1 to death in this 286 along with Ultimate VI and Martian Dreams. And also had the opportunity to play Access Software classics and Accolade games on this too.
And some time later, the 486DX2-66 were deemed king of the 1st class computing at that time, and I wowed and wondered about it and dreamt ever since of having it. It ran all the "most demanding" games as smooth as butter when released. (Of course. DOOM and later Quake seriously challenged it's power.) But by that time I was about to go to college and I didn't have chance to get it.
And when I came back for a big break during college, I had the opportunity to get the legendary (for me) Pentium 133. With it came the CD-ROM drive, which totally immersed me in the speech and animation enhanced versions of previously played games. I couldn't have gotten it at a better time than that, since it was the era of "multimedia" explosion. Windows 3.x had many "multimedia" CD-ROM applications, utilities and games.
I had lots of memorable moments with it, even though it was just a Socket 5 system.
After started working, I built my first 486DX2-66 system with parts from EBay. And continued to keep the same Pentium 133 system till this dday.
