I can hardly remember those times , the windows 3.1 was a thing but 70% I had use the dos version , I m not sure if this was dos but it had a cmd line and a blue screen no mouse , when I was a little kid thats how I managed to open games .You've got me hands down on that one, Paul.
Mine was an 80286 (286-AT) with a 40MB HDD, 1MB RAM, 12MHz refresh on the clock.
2 floppy drive bays, one for 3.5 inch, the other for 5.25 inch. Now those were floppies!
Windows 3.1 was the OS

And I remember the magical "speed" button on my PC , my computer had like 16MHz after you pushed the button it changed to 32 MHz you even had a little "monitor" for the speed on the computer .
