Tom,

Jim Haynes can probably confirm this... You could be looking at a 
typebox for a Model 29 which was an outgrowth of the Model 28 with 
the standards committee wars with IBM and the Bell System.  As I 
understand it IBM wanted an EBCIDIC coded machine...  i.e.. an 8 
level model 28 with special typebox and special characters.

There were also specially coded typeboxes for Model 28s that 
interfaced with the No. 101 ESS machine.  The characters made no 
sense except to the coder and the ESS.  The keyboard had more blanks 
in it than keys and the space bar was a printing character.
