And BTW, the correct answer as 90 or 144 for the hexadecimal-challenged.

No, Craig, nine was the answer to your question. Now, had you asked for the
"Turbo-Nerd" answer to your question then the answer you provided would have
been supplied (of course, not by me). :-)
Have a great Holiday weekend to all!!

I questioned first, then googled, must do that in reverse next time.
Here's the answer for those wondering...
A5159A - Dual Port FWD SCSI-2 (PCI Bus) Adapter Card. (N-Class Only) This
card plugs into a PCI
Bus on the system and presents two (2) independent SCSI buses to the outside
world. These SCSI
Buses allow connections to High Voltage Differential (HVD) SCSI peripherals
only. (Historically on
the HP e3000, HVD SCSI devices have been called "Fast/Wide" devices.) Each
of these buses must be
terminated using an HVD terminator; typically this is a High Density (HD)
68-pin HVD Terminator
such as the C2905A. For details see "HP A5159A Dual Port PCI to Differential
Ultra SCSI Host Bus
Adapter Service and User Guide."
A5150 - Dual Port Ultra 2 SCSI (PCI bus) Adapter Card. (N-Class Only) This
card plugs into a PCI
Bus on the system and presents two (2) independent SCSI Buses to the outside
world. These SCSI
Buses are capable of operating in either LVD or SE Mode. This determination
is made automatically
by the card based upon the devices and termination present on the Bus; there
is no software
control for this feature. Each SCSI bus must be independently terminated.
Depending upon the
cables/connectors being used this would typically be either a High Density
(HD) 68-pin LVD/SE
terminator such as C2364A or, for Very High Density (VHDCI) 68-pin LVD/SE
cables, a C2370A. For
details see "HP A5150A Dual Channel PCI to Ultra2 SCSI Host Bus Adapter
Service and User Guide."
