The AT&T UNIX PC runs a version of UNIX that's somewhere between SVR2
and SVR3.
It was built by Convergent for AT&T until around 1986. The machine was
unloaded
on AT&T employees and via liquidators (companies that sell surplus equipment)
after AT&T stopped marketing it. It's still a useful machine (I have two) and
wins the prize as the world's cheapest UNIX box. Here's a sample hardware
Processor: Motorola 68010 - 10 MHZ (~0.75 mips)
Memory: 2 Megabytes
Hard-disk: 40 Megabytes
Modem: 1200 baud (internal)
I/O ports: 1 Serial
1 Parallel
Display: 720x380 pixel monochrome bit map
Keyboard + Three button mouse
There's an active group of both hardware and software hackers around
the U.S. dedicated to keeping the machine alive and useful. As the
previous poster suggested, the best place to look for UNIX-PC information
(including FAQ's) is the news group comp.sys.3b1
