Yes, there is a double row of jumpers labeled as stated. This jumper block
J5. With no jumpers on any pin, you will have an ID=0 for this controller
card. Other ID's are set as follows:
	CONTROLLER #1	A-B
	CONTROLLER #2	C-D
	CONTROLLER #3	A-B and C-D
	CONTROLLER #4	E-F
	CONTROLLER #5	E-F and A-B
	CONTROLLER #6	E-F and C-D
	CONTROLLER #7	A-B and C-D and E-F

This will give each controller a unique SCSI ID number as they are
daisy chained together. If you decide to connect multiple 4070's be
sure to remove the terminator resistors RP3 and RP4 from all but the
the last one. 
In the past, I have done this so that each 4070 has the SCSI ID number
and two RLL drives connected to each 4070 would then have a LUN of
0 and 1 respectively.
