Another couple of thoughts on the same subject.

Germany, seems to be giving us the functionality of selecting pumps #1
and #2.  To reduce the amount of rework in my system I propose the
following.

1.      We keep the selection of pump #1 always on.  It would be
hardwired on.
2.      We give up a digital output "computer controlled hpu estop"
(after Rod's rewiring this is current).  We use this digital output to
control the selection of pump #2.
3.      The HPU estop chain would be directly tied into our MTS estop
chain (via Rod's K8 modification).  Therefore, we would have to reset
the MTS chain
        prior to reseting the HPU's chain.
