DZ shuffle
The sixth DZ (F, the perhaps-flakey one) has been exchanged, temporarily
at least, for the one (A) with the bad port.  The intent is to give Wern
a chance at fixing the bad port, and to perhaps find out if DZ F is really
flakey or whether the bus is just overloaded by adding another DZ.  If
it's the DZ, the symptom will be an upswing in the CP-HUNG crash rate.

I also took the opportunity to plug the card reader cable into its
interface, as we may need to make it operational soon.  The thing has
been out of service for quite some time because the cable is too short
to reach the only convenient place for the reader;  this is still the
case, so if we need it we'll have to move it temporarily to somewhere
the cable can reach.

An interesting observation in the course of bringing the system back
up:  if you forget to switch on the power to Star Ring et al, you can
get the STRANGEST symptoms when you try to boot (e.g. the SMC screws
up in such a way that it looks like the disk DRIVE is not responding).
