I have a very bad copy of some relevant pages from the 706A manual (which 
is what yours now is presumably)

You can create a 'virtual' terminal connection from the console prompt as 
follows:
 >>> D/P/L 20088004 80000001
 >>> D/P/W 20001f40 20
 >>> d/p/w <addr> 3FFF
 >>> S 200

What this does is create a I/O mapping, then enable it, the tell the 
controller to load the monitor program into memory, and then execute the 
monitor.

The <addr> field is the address of the SA register on the controller.

I'm guessing it is one of:
         2000146a
         200000de
         200000ee
         200000fe
(depending on if the controller was last configured as the 1st, 2nd, 3rd, 
etc. If it is showing up as the first one then the 2000146a address should 
be correct.

When you type S 200 the formatter diagnostics should start.
