:-) I put my hands on some SCO systems at some customers' and I think
Linux is quite _another_planet_ (and among every distribution Debian, also
used Yggdrasil, Slackware and RedHat).

Yes but a terminal does NOT go down unless broken, while some of those 386
could go down... ok you may say "we have not only one while the main box
is only one"... why should it crash (provided you put a power supply
backup of course), I mean why more likely than those 386's? Because it
does that lot of things? Then I would have it just handle the sessions on
the terminals and the dbase and would connect _another_ box via ethernet
for the other tasks. What do you think?

Yes, not wrong (though I see you resent the posting without this note
:-)), but I collected help from very high quality people here (some "big"
one via private e-mail), and there could be some Debian package I'm not
aware of, and some of the original questions involved Debian-tested
hardware.
