This brings up a source of confusion for me: Where is the X terminal
getting all of the information and guidance it needs? If I use a Sun
workstation as an X graphics server, for example, the X window manager
runs on the Sun;
Using an X terminal, you first start an X window manager on a Sun or other
host that has X window management software. Then you start the Symbolics
console as an X window controlled by that manager.
fonts are read off the Sun's file system;
The NCD, GraphOn, and Tektronix all read fonts off the Sun file system.
Remember these terminals are highly powerful computers (often 68020's with
8MByte memory). The terminals require your X startup files (e.g., .xinit) to
setup the font path information (xset fp+...). The Sun that is running the
window manager runs the startup files. The terminal controls font requests
the server's Internet address is the address of the Sun host;
The X terminal has it's own internet address. The X terminal is the X display
device that you pass to X programs and set as the DISPLAY environment. The
terminal is not a device of any particular Sun host but has it's own unique

The window manager determines what access permissions are required. You type
'xhost ...' into a xterm that accesses the machine running the window manager.
graphics parameters are set from startup files in the Sun's file system;
Yes, the Sun running the window manager handles this.

this X support? If the Symbolics itself, is there documentation as to
how to configure and administer an X terminal from the Symbolics?
The Symbolics does almost nothing (don't flame me) with regard to window
management and X. It is just an application not an X server.
(Perhaps I don't understand enough of how X functionality is divided up
