That sounds exactly like my first computer. I think I was about 13 or so. I forget. BUt yeah, my first PC was a 286, 5.25" floppy. I remember when the 3.5" floppy was new!
Lol. I graduated high school in 1991. As a graduation gift, my parents got me a new PC - all the pieces. So I had to teach myself how to build a PC from the parts. Probably one of the best gifts EVER!
It was a 80286-16, 5.25" & 3.5" floppy drives. It had a CGA graphics card as the VGA cards were ungodly expensive at that time - I commonly called the CGA graphics "Crayola Graphics Adapter" as it is only 4 base colors if I remember right. The big part was the 40 meg hard drive that they got me.
They also got me DR-DOS 5.0.
So once I got it built, then I had to get a crash course on how to configure it via the autoexec.bat and config.sys files to get rid of IRQ conflicts. FML!!
I remember later on playing Leisuresuit Larry, Kings Quest, Space Quest, then after a couple of years and some hardware upgrades EPIC Pinball, then Doom (mind was blown) then Doom II - all the Quake's, etc. Man I miss some of those games. Quake II especially.
