I have replaced 7 dumb terminals with 486 Linux PCs running tn5250 on the
console (Alt-F1).  Two of the machines are used in the Admitting Dept (we are a
hospital) which runs 24x7.  Once my users got used to the few keys which where
different they didn't care.  They even like the brighter screen and some of the
colors they didn't see before (there's a purple strip in one area).

I am also able to do other things with it as well.  I have a few machines which
use the Alt-F3 console to run a telnet session to a SCO Unix machine to do lab
result lookup.  The other machines use Alt-F3 to do a 3270 session for insurance
verification.  Alt-F2 uses Lynx to connect to my Intranet Webpage which allows
them to do paging.  The Intranet server is a Linux server which also has Qpage
installed on it and a web front end I created to do web-based paging.  All of
this would not be possible with dumb terminals.

These machines are all 486s with 12-20M ram and 250M disk drives running a
stipped RH 6.1 install without X windows.  The install image is about 100M.  In
the next few months we will upgrade that to a RH 7.1 (maybe 7.2) with all the
same software.  The only reason for the upgrade is just to keep it current.  The
existing install has been in constant use since 1999.  The only problem was when
one of the 486s died and we had to grab another out of storage to replace it.
