That shouldn't happen unless the Keyboard Interface PCA is strapped for 
"compatibility mode."  Open the unit, pull the Keyboard PCA, and check the 
DIP switches at the top of the card.  Switches P and Q should be set to 0 
(closed) for normal operation.

With both closed, the terminal should power up in alpha text mode.  Then it 
may be switched to graphics text via an escape sequence or by the keyboard 
TEXT key, as desired.

(I have an HP 2647A.  P and/or Q are set to emulate a Textronix graphics 
terminal.)
