Wiring terminals 300 ft. from the computer

[Jennifer Freeman]

A company I am doing some work at needs to do some office rearanging as they
are rapidly filling up the space they have.   They are also about to get a
multi-user Unix Box running on a 386 or a 486.  One of the proposals is to
locate the computer about 300 feet away from where the bulk (10-14)
of the terminals will be.
What type of wiring would be needed for this?  Would shielded be
good enough?  Would some kind of line boosters be needed?  We have some people
with knowledge of micros, but not in wiring multi-user systems.  Any suggestions
things to look out for,  tips etc would be much apriciated.
