I am proud that in my x86 computer history I had the opportunity to use Dos back in time correct period with all the well known games from early 90's but also some late 80's (like Alley Cat, oh man..).
The first x86 pc I've tried was a quiet new expensive Compaq 486SX (I think 33Mhz) friend pc with 4MB of ram and 107MB of disk back in '93/94 I think. It's funny that I used for long this faster machine before we got our first x86 and cheap pc that was a 386SX 16/20Mhz plastic cpu based,1MB of ram and a slow Oak isa vga card and something like ~40MB of heavy and big disk. I have great memories of Stunts,Jill in the jungle, Prehistorik,Another World,Motogp,Indy 500,Zool,Wolf3D (not full screen) and others... I used this (only upgraded to 4x1MB 30pin expensive simm) until the 1998 for a just released K62-350 pc.

Of the missed things are both the biggest games names like Doom 1 and 2 and Quake in the time correct moment cause it was not possible to run it on my pc. I remember seeing Doom 2 on another 486 (probably SX2 50Mhz) in SVGA/high detail. It was incredible. I totally missed the first Quake until I had the Voodoo3 on the K6-2.

My very first computer was PMD 85 (8-bit personal computer produced from 1985 by Tesla in the former Czechoslovakia) with these specs : CPU = MHB8080A 2.048MHz /48 KiB RWM and 4 KiB ROM .
And from the 088 era it was 386 sx20 (Compaq desktop Series 3021).
ooh those days...

Multitech/Acer 710 XT clone, late 1987. 2 flops, no HDD. Samsung MD-1252G 12" amber monochrome display, Okidata dot matrix printer. Kept unit in billiards room. Had ATI small wonder integrated into board. DOS 3.2, used MS Works & Typing Tutor for school. Played Test Drive, Space Quest I/II, various small games like monopoly and blackjack. Was disappointed with unit as lack of color display and no hard drive. Had to go to father's office in downtown Buffalo to play games in color on weekends.

My first x86 was bought new in '90 was mini AT 286/16 based system with 1megs of ram,OAK vga video card, 40meg hard drive and 14" vga monitor. Learnt fairly early on that the hard drive wasn't going to cut and bought a 240meg HDD some time later, then got 4x1meg SIPPs for use with Geoworks Ensemble Pro 1.2(it ran fine with 1meg) and later Windows 3.1. I had a lot of fun with that system.

Had it a number of years in that configuration before swapping out the for a 486DX based mobo I got second hand when a work college who updated his system to a pentium. I repurpesed the SIPPs by removing pins bring it up to 8megs.

My first PC was a Commodore P10-III 8088XT if I remember correctly. Had no HD, Hercules monochrome and 2x 3,5" floppy drive. Upgraded it later with a VGA card and monitor. Don't remember correctly if I bought a SB 1,5 or 2.0 for this one or my next one, a 386DX-33.
Hoping to rebuy 'my first PC' one day......
