I began thinking about operating an open-access UNIX system after
brought up gorn in 1988,
running SCO XENIX 2.1.3 on a lowly 4.77MHz true-blue 8088 PC.
It became a more real possibility after (as Jon had) I went to work for
SCO, late in 1989.
Early on, it ran on relatively low end hardware, some of it rather
Nowadays it's more stable, though still using a motley assortment of hardware,
some new, much bought via the net and at
And of course, there is still the occasional
The most significant thing to happen to the system since it was brought up was
the connection of our house Ethernet to the Internet.
This had been in the works for years, since before we even had a network,
or any UNIX systems for that matter, but connecting to the Internet in the
early 90s wasn't a simple matter.
Shortly after moving into the Armory, we applied ourselves toward connecting
our house to other local houses that we had line-of-sight to by various means
(first infrared and then
Some interesting experiments were done but none of it panned out.
With the same group of people, we considered a
commercial IP connection, but the IP vendors'
policies made that unworkable.
Finally, in 1993, the same folks took matters into their own hands and founded
Santa Cruz Community Internet (later absorbed by Tycho Networks, then DSL.net),
which made their and our long-sought goal a reality.
Here's a brief history of the system.
