I have two Simms I think they are from a SGI machine. Strange, these seem
to also work in the Cube. Should be 36-bit, thus party, right? Maybe they
were in the wrong box at home, if not, then seems like at least the cubes
accept a much wider range of RAM than Sun claims to.
Anybode here can tell wheter the Qube DOES accept this kinda RAM?
