You can run a machine without swap, although most systems scream in agony if you try it. That’s the Pentium running everything in only 10Mb of space — X, htop, Musca, an emulator daemon, and even elinks.
How’s performance? Completely unusable. But fun to look at, even if it does make me scream in agony if I try it.😀
