The original question had to do with building a network for CAD
purposes, and stated that the current setup is 286's running DOS and
AutoCAD.

If the upgrade machines are 386's, and they buy AutoCAD 386 for DOS, it
*supposedly* will run VERY fast.  However, it remains to be seen what
sort of network you can set up.  We are building a similar system
(286's, new 386's, and SPARCStation 1's) which will run AutoCAD and
NFS/PC-NFS.  Our initial research led us to building a system based on
DOS on the PC's and SunOS (of course) on the SPARC's.  The choice to run
DOS was based not on AutoCAD but rather on commercially available
Finite Element Analysis software... we were unable to find a really good
386 Unix based software system for this, and a DOS based package specifically
for the 386 *is* available.

(There may be such software available now, though.  We are dealing with
government contracting... so the actual specs were written a while back.)

In other words, I'm not contradicting Bill, just pointing out that the
"best" choice often does not work.

The BBS address is because we don't have Internet access where I work...
