Gould PN UTX also installed itself with a "no-swap" kernel,
just a stripped down version of standard Gould UTX running out
of a ramdisk. 
    There was no reason it couldn't run X, if you had enough
physical memory; we didn't include X in the ramdisk image, but there
were tools so that the user could build his own noswap system.

Motorola System V/68 also uses a ramdisk type installation.
