Ok, Ethernetters, AppleTalkers and PCRouters, here's my problem.
2
What I've got:
Two separate networks, one on 10Base2 carrying NFS (TCP/IP) traffic,
and connected to the world via PCRoute, and one on the original AppleTalk
cable running TOPS.
I have the following software: TOPS (Mac & PC versions), AppleShare PC,
PCRoute 2.1 (Thanks to Vance Morrison for some great software!), PC-NFS,
NCSA Telnet 2.3?? (Mac and PC versions), MacTCP.

What I want:
The two networks bridged through PCRoute, providing telnet access from
the Macs to the Sun4 and the rest of the world, and access to the
LaserWriter from the Sun4.

Background:
I set up and installed the networks myself, and learned of and installed
PCRoute to enable us to connect to the outside world. This was done
because it is unquestionably "a neat thing" but was done essentially with no
support or blessing from the powers that be (other than coughing up the bucks
for two WD8003E cards).
Given such a tremendous lack of support a $2-3K FastPath, GatorBox etc.
is out of the question. I _might_ be able to spend $500 in several
sureptitious increments. Again, my main reason for wanting to do this is
that I feel it is "a neat thing" AND I really want to be able to print to that
LaserWriter from my Sun4. This is real hard to justify to the powers that be
who purchase a PC to be used as a dedicated HP Laserjet server!!!
According to the documentation for PCRoute:
"PCRoute supports IP inside of LocalTalk. This allows you to send
IP packets through LocalTalk nets.... In addition any Macs on the
LocalTalk network that have MacTCP can access the IP network.
Note, however that PCRoute does NOT support encapsulating AppleTalk
in IP (thus Ushar and CAP will not work), and does NOT support dynamic
IP address assignment."
The docs further say that PCRoute does not access the LocalTalk card
directly, but instead goes through the device driver (ATALK.EXE) that
comes with the card. (Hah! my card had no such beast, because it didn't
come with a disk!)
PCRoute has been configured for two Ethernet and one AppleTalk interfaces,
and appears to start-up correctly. It does correctly (and quite amiably) pass
Ethernet packets (you got this didn't you?). However, I have tried using
MacTCP and don't seem to be able to talk to the Ethernet from the Macs.
I have both a genuine AppleTalk PC card and a TOPS Flashcard available.
Currently the Flashcard is installed in PCRoute because the AppleTalk card
will not work at bus speeds above 8MHz and I am using a 10MHz XT to run
PCRoute. Trust me, it doesn't! (The 8MHz XT motherboard I have will not
work with the WD8003E cards needed. Why? Beats me!)
Below is my PCRoute log file. I know the LocalTalk interface has the
same network number as the second ethernet interface. I'ld prefer not to
have to get a new number. Please don't tell me that's all there is to it.

Cry for HELP:
Is there anyone out there that is real familiar with PCRoute and can help
me set up things correctly? Any ideas regarding how to print to the
LaserWriter? Can this even be done? I've exhausted my campus' expertise,
and they all say it can't be done, although noone around here has tried it.
Assuming it CAN be done, it seems there are a lot of people out there buying
FastPaths and Gatorboxes that they don't need!
Any help would be greatly appreciated and I'll be happy to post a summary.
