[pups] Help! Standalone DZ-11 driver

That's why I've inquired of Warren about using the DZ-11 as the
pseudo-device. I also have a console input (DL-11, from memory). The input
silo is potentially a benefit, but it's not a panacea by any means -- it has
to be handled pretty carefully. -- isk

I don't have a PDP-11, but I have done work in various ways with
remote-device installs. If it were me I would prefer to be able
to use a device distinct from the console, for several reasons:
- a separate device might have an input silo (e.g. the DZ11 does);
the console usually doesn't. A silo offers a little more robustness
and may allow greater speeds.
- it is better to keep the console available as a place for error
messages to show up when things go wrong.
- things are going to go wrong in any case, and I am going to have
to try booting several times. If I have to get a serial-line switch
or move cables back and forth, that is another thing that can go
wrong, and another thing I can screw up.
On the other hand, if I had the problem I would likely be happy to
get any code that would help, whichever way it worked. So I also
favour letting the implementor choose.
