My Archive 2150S manual has a different jumper arrangement

	RXD TXD o  o     o  o CF2      o  o ID2
     (not used) o  o     o  o CF1      o  o ID1
	Parity  o  o     o  o CF0      o  o ID0

The RXD and TXD are for connection to a terminal thru
a level changer.

The CF0-CF2 are jumpers for determining the "Disconnect Size"
or the max number of bytes that can be transferred over the 
bus during a single Data Phase.
	0H	2k bytes
	1H	4k
	2H	6k
	3H	8k  (minimum reqd for COPY command)
	4H	12k 
	5H	16k (factory installed)
	6H	24k
	7H	32k

The ID0-ID2 are the SCSI ID.  Don't use 7 which belongs to
the controller card.  Note: 0=lowest priority.
