I have linked the X to the Xcfbpmax xserver executable using the command 
given in README.pmax.  I was finally able to get xinit to run.  The error 
about the font path resolved itself when I realized that I needed to do:

xinit -- -fp tcp/localhost:7100

and NOT

xinit -fp tcp/localhost:7100

Newbie mistake.

This did not work from the console the first time.  I logged in via a 
telnet session (from my PC) and killed the Xserver.  I then ran xinit 
again.  X comes up with an xterm (no window border) and a mouse crosshair 
in the middle of the screen.  No response to input from mouse.  I'm afraid 
I'm stuck again...

I will provide more info on hardware if someone can tell me where to look 
to find out what version of the baseboard video I have.  I know that it is 
a color board (I've been using the machine under Ultrix 4.4 for a while). 
 I have a color monitor on it, VR-299-DA.
