386i - Roadrunner
No the Sun 386i (aka Roadrunner) was not a pizza box rather a mini tower. They were designed by the Sun "East Coast Division" to be easy to configure out of the box. ECD did a great job and came out with what they called Plug and Play which meant you took one out of the box, stuck it on a network with other Roadrunners and they all justed worked together. No Unix command lines needed to manage them just a set of gui tools - way ahead of their time in a lot of ways.
Sadly ECD were out on a limb in Sun and all the great stuff they did worked well between Roadrunners but they did not play well with other Suns (or other Unix workstations for that matter) and most of the stuff they did got lost in Sun politics. A real shame as the dynamic configuration stuff they did was very innovative.
