Michael should certainly know.  He's one of the people who worked on the VAXeln
window server.  (I don't know if he still does)



The Model 76 is not supported as a VAXeln window server for a variety of
reasons that I won't go into at this point.   However, what you can do is
to make the Model 76 with VMS (barebones VMS by the way) behave as if it
is an X terminal.  Here's how you do it:


1:	Fix your startup to call some procedure that behaves and works
	with the VAXeln window server DCL script that starts the remote
	session.  Take a look at the  VAXeln DCL and you should have a 
	pretty good idea of how to make your DCL talk to its DCL.  You will
	probably have to hard-wire the "server" name since you won't 
	be booting from that server

2:	edit DECW$STARTUP.COM and remove (or comment out) the line that
	runs DECW$STARTLOGIN.EXE.  That's the piece that puts the login
	box up on the screen.  You won't need it. 

3:	Create the file DECW$SERVER_ACCESS_TRUSTED.DAT   and 
	insert HOSTNAME::SYSTEM as one of the trusted clients that will
	be able to use and change the security of the server on your 
	machine.  SYSTEM will run the  login box, and change the secuirity
	list during the login process.  (There is also a 
	DECW$SERVER_ACCESS_ALLOWED.DAT, that allows access, but not 
	allow changes to the security list)

Reboot the machine.



You won't have all of the features.    You could use the same server to boot
the machine into a VMScluster and use that bootnode info to find the name of
the node where you want to start the session, but that's an exercise for the
reader.
