DEVICE DESCRIPTION
  
THE 10 INTERRUPT CARD IS A HARDWARE HACK USED BY THE PDP-11 TO
INTERRUPT THE PDP-10.  FOR THE PDP-11 TO INTERRUPT THE 10 ALL THAT IS
NEEDED IS TO WRITE INTO LOCATION 772566 WITH THE LEAST SIGNIFICANT
DATA BIT TURNED ON.

  EX:
	MOVB	#1,LOCX			LOCX=172566
  or
	INC	LOCX

A BUS RESET FROM THE PDP-11 [INIT L], RESET FROM THE PDP-10 [RESET],
OR A CLEAR INTERRUPT COMMAND FROM THE PDP-10 [CLRSPINT] WILL CLEAR
THE INTERRUPT.  THE INTERRUPT CAN ALSO BE CLEARED BY WRITING INTO THE
INTERRUPT LOCATION WITH THE LEAST SIGNIFICANT DATA BIT TURNED OFF.

THIS DEVICE IS BUILT ON A W943 2 PADDLE DEC WIRE WRAP BOARD WHICH
PLUGS INTO THE 10/11 INTERFACE RACK.

NOTE: IF THIS LOCATION IS READ AN INTERRUPT WILL NOT BE GENERATED AND
AFTER A BUS TIME OUT (10us), PDP-11 PROGRAM EXECUTION WILL CONTINUE.

To use this interrupt see uuo.upd[s,doc] item # 123.
