[comp.unix.xenix] 80386 20/25/33, input, multiport cards

danielw@wyn386.UUCP (Daniel Wynalda) (08/02/89)

I have been recently asked to acquire/develop a new system for use in our
production plants.  With the advent of the newer, higher speed 386 machines,
it leaves me with a few questions. 

Could I please get the kind input from a few of you on the advantages/problems
encountered with the 25Mhz+ machines?

I am going to have this machine (using intelligent I/O cards) monitor
a few of the devices on our plant floor.  I'll be writing the daemons and
running an occasional program in "cron" under 386 SCO Unix (or Xenix) to
analyze and transfer the data.

Could someone please give me input on the advantages of the 386/25 and 386/33
machines around, and whether I should spend the extra $$.

I would like to connect the new machine to our current SCO Xenix 80386/20
machine with Mylex motherboard.  This connection will, hopefully,
be TCP/IP with Xenix-Net from SCO.  Could someone please give me input one
your configuration of TCP/IP (Whether you are using Excelan etc) and 
your input as to what you can reasonably expect from this network.

Also, we have a few DOS machines that act as terminals on the current
80386 machine.  If we begin to run TCP/IP and Xenix-Net on our machines, 
could we link our PC's via SLIP (or other linking method I guess) and get
them to use the Xenix machine as a FILE SERVER as well as allow remote
logins?  I realize I could do it by buying another ETHERNET card for
the DOS machines, but I'd rather run over a twisted pair cable for as often
as I would do it.


Any input on the subject of TCP/IP, Xenix-Net, and 20Mhz+ machines
would be greatly appreciated.


		Thank you
