Re: Minifridge

Well, Hevi,

my notes on hacking C2 passwords are down in Window Rock.  Where I lived and
worked many years.  Now I am at Fort Hall.  GIS means geographic information
system, originally a set of network topology and data base programs running
under a shell called ARC.  

The Alpha was the first box that would ru the topological operations fast
enough to preclude a cup of coffee between the time you hit return and the
time the command finished executing.
