SW was never release on floppies. If you rip all animations off, it could be boiled down to like 38MB, 24MB compressed. So in theory it could be stored on like 17 floppies.
For original Syndicate, you can use DOSBox to play the original, of Freesynd project for native binary, Freesynd has some noticable improvements, but it is unfinished in some areas.
