No idea on the specs of the computer, but it ran MSDOS and Windows 3.1. It was my dad's computer, but he had a load of different games on it. The most vivid in my memory are the King's Quest games, alongside Rescue Rover 1 and 2 (amazing games that no one seems to remember), Gods, Lemmings, Zool 2, and Mario Bros. I don't know how or why Mario Bros. was on this PC, but it was.
One of the earliest photographs of me as a toddler is when I fell asleep in front of this computer, right at the desk. I used it a lot.
