I remember we got our DOS computer second hand, it was from a friend in exchange for a few pints of real ale. I think it must have been 1993 and it was old for the time, but I remember it having 8mb of ram which was something its previous owner was very excited about, it had cost him £50 per mb and he had upgraded from 4. It must have been a colossal amount of memory for the time as the hard drive was only 100mb!
Growing up I remember the game that you had to upgrade your computer for great expense for, the 2 I remember the most are half life 2 and then later crysis. Do you remember any games that you had to upgrade specifically for/were just impossible to run on anything but the bleeding edge? You mentioned Doom, I can see that being one
