Back in my day, I had to hack up my underpowered 486 in order to get Doom to run decently.....knowing the ins-and-outs of what drivers to exclude from my autoexec.bat and config.sys files in order to have enough memory to run it. I learned a good bit about memory and learned quite a bit
Same. My first real computer was a 486. I didn't have the required RAM to run Decent, my most favorite game of all time. I figured out how disable the memory checking and was able to run the game at home.
The bigger the theory the better.
