It's nearly 10 years ago now since I've been (for 10 years) on CDC CYBERs all
day & nite ... but I still miss them every minute! First running NOS, but then
additionally (in dual state on the 180) NOS/VE with its clear command syntax,
builtin ACLs with access logging, accounting, file cycles, nice file attributes
such as FAP (file access procedure), completely separated user environments
(as you describe), programming language CYBIL and command language SCL, ring
architecture, and so on. How many, many stupid problems of nowadays were
avoided simply by good design!
