Having started in the 386 era, and having upgraded my AMD 386 from its original 2MB of RAM to the full 8MB, my first reaction on seeing that "64MB SDRAM SIMM-72" spec in this article was "wow, that's a lot of RAM!"
72pin SIMMs we're plain async DRAM and later EDO. Never SDRAM.
Ok my mistake, edited the post to just "RAM".
Swap is activate pretty late in at 5:59 and you can clearly see there isn't much disk activity going on.
A barebones debian installation should be using < 50Mb at boot, so a custom gentoo could be <40Mb
