I have one taken out of a VAX 11/780, and my inventory records indicate
it is an M9400-YE.

The complete complement of boards in that machine, in slot order:

M7264-YC  	(CPU)
M7946		(RXV11 floppy control)
M7940		(DLV11 serial port)
M8400-EH	(Memory)
M9400-YE	(Terminator / VAX Interface - presumably has ROMS too).
