Mixing Macs, IBM-PCs, LaserWriter on lans

[Peter Day {EUCC}]

One of our departments intends to put in a number of workstations.  I
expect them to connect the workstations together using ethernet and
TCP/IP.  The faculty have Macs and IBM-PCs which they would like
to be able to use to
communicate at high speed with the workstations, each other,
the workstation server, and some laserwriters.  One possibility we are
considering is putting the Macs and Laserwriters on an AppleTalk net
and bridging the net to the ethernet with a Seagate bridge.  Presumably
the Macs can then at least do Telnet and FTP to each other and to the
workstations.

The question is what to do about the IBM-PCs. A product called
MacBridge will allow the PCs to use the AppleTalk net to print on the
laserwriter and exchange files with the Macs. However, I have not seem
a TCP/IP implementation for a PC that uses AppleTalk. If the IBM-PC was
connected directly to the ethernet running say the MIT TCP/IP package,
could it still print on the LaserWriter? Is there some way to use the
workstations or servers (say Microvax II) to act as spoolers for the
LaserWriters and allow any of the machines (Macs, IBM-PCs,
workstations) to spool to them easily? Is there a solution if the
microvax II is running microvms?
