I just read that some of the first CAD software ran on computers with only 64KB of RAM

Found this on a tech history blog last night. They were talking about early 80s systems like AutoCAD 1.0. It's wild to think people drafted entire buildings on that. My current setup has 32GB, which is like 500,000 times more memory. Makes you appreciate how much the tools have changed, even if the basic job is the same. Anyone else come across a fact like that that puts the old days in perspective?
