Note Since the P2 adaptor card for the MVmE712M is a three (3) row connector, signals on Rows Z and D are not routed to the MVME712M. Thus

(a)although the IPMC712 controller is capable of 16-bit (wide) SCSI operations only 8-bit (narrow) transfers are supported through the MVME712M

(b)PMC I/O from site two (2) is not available through the MVME712M

(c)Please remember the caution stated on page 5-25 that a PMC located at site two (2) may not connect to pins J24-2, 5, 8, 11, 14, 17, 20, 23 and 26.
