[net.micro] LAN Purchase and Planning Query

cptcam@amsaa.arpa (02/23/86)

I have been given the task of planning a proposal to establish a LAN
of micros for my office of 20 analysts.  We currently use 7 dumb
terminals on a hard wire to a VAX/UNIX system.  We also have a
dedicated word processor and 4 printers of various quality.  I
envision a system that permits us to keep as much as possible of the
current system and maintain selective interaction with the micro based
network.  In other words, both micro based and mainframe based usage
for all terminals, sharing of printers, interaction with the word
processor...

Questions?
1.  Can I avoid using a consultant?
2.  Is it possible to consider integrating the dumb terminals?
3.  Is it possible to integrate the word processor?
4.  What hardware, aside from the computers, hard drive backup, additional
printers and monitors is required in a LAN?

Parameters:
1.  Ratio of terminals to analysts is to be 1/2.
2.  Ratio of printers to analysts is to be 1/4 (DQP mostly).
3.  Graphics, statistics, spreadsheet, database, project management, word 
processing, mathematic modeling, and CAD are the common interactive
applications we perform.
4.  1st brainstorm says use 1 PC/AT, 3 PC/XT, 6 PC, 7 existing dumb
terminals, 4 existing printers plus 3 new printers, hard drives in the
AT and XTs.
5.  Cost is not a limit yet.

What I need is some good opinions, experiences, and a better feel for
the technology involved.  Please refrain from brand name references as
we will shop later based on what we learn.

Thanks to all who can help.
