What is an att 7300

[Grant Balkema]

I have the chance to pick up three att unix computers.  As usual, they
are a thousand miles away and nobody there understands what they are,
other than a secretary who said it had the number 7300 on it, and she
thought that it had a hard disk in it.  The listing said ATT unix computer. 
Are these worth anything (my cost is shipping) what UNIX do they use? system
V? can ethernet them? What chipset microproc' do they have, etc. etc. Any
comments at all!
