I have a SPARCstation SLC, so I can give you a little info.  It's a Sun 4/20
architecture, meaning it's a SPARC processor running at 20 MHz.  It has no
built in disk of any kind; they were meant to either be connected to an
external SCSI disk or (more commonly) network booted off a central server. 
Video is a black-and-white framebuffer driving the internal 17" monitor.  It
also has 12-bit uLaw sound, two serial ports (on one DB-25 connector), and
an AUI network port.  16 megabytes, in the form of 4 4-meg parity SIMMs, is
the maximum amount of RAM.  The serial port pins are configured so a normal
cable plugged into the DB-25 port will connect to the proper pins for port
A.  Port B requires a special splitter cable.

IIRC this was Sun's first computer that sold for under $6,000.  It features
completely silent operation.  (No built-in disk, and no fan.)

It will run Linux, NetBSD, OpenBSD, or SunOS 4.1.4, all of them slowly.

No, I don't want another one. ;>

I don't know of anyone.  They're pretty common, as Suns go, since they were
popular with colleges.  I once bought a lot of 10 for $15 at a surplus
auction.  (Some wag asked me if I planned to set up my own computer lab.)
