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.
Real computer scientists don't comment their code. The identifiers are so long they can't afford the disk space.
