For these four demos I don't know, but part of the challenge was certainly working within the constraints of the machines of the day. The Furture Crew demo I believe comes in at 2.5MB and ran on a 1993 PC, so probably 8MB of ram at the most. Running it in the browser is probably at least 20 times the memory.

It's really cool to be able to rewatch these demo, but the spirit in which they were created is somewhat lost.

Second Reality ran comfortably with only 640KB RAM using the Gravis Ultrasound.

But it did require a 386, which typically had 2 MB or more of RAM back then.

Second Reality runs in real mode, and doesn't use XMS or EMS so it runs in 640kb!

It was also ported to run on a Commodore 64 back in 1997, in 64KB

		Yes! Personally I think that's a much more interesting homage.

lol, that would be 160MB then, a fraction of what a Firefox Tab consumes and in todays hardware specs its a roundoff error :-D

(while back then you were the ultimate king if you had 8 MB of RAM available at all! :-)
