I remember when Doom Ultra HD 8k came on 40k floppies. Back before we even had 2k displays. It took nearly 2 days to read it all into RAM (mind you, I had a cluster of 200 computers just to *have* enough ram...) and ran at about 0.01 FPS on my 640x480 CRT. And you had to read about 73 more floppies every time you loaded a new map. Ah, the good old days.
