Unix really is a significant improvement, we really need to make sure you can
run it. Don't worry about the OS image issue, I can crank them out like
sausages, and we already have all the bits we need (V6 RL driver, bootstrap,

Really? DEC specified BC08R-01 cables, which _should_ be long enough to allow
it to be put on an extender. Does your machine have the -01's, or have they
been replaced with little shorty ones?
If the latter, if you can't find any -01's, it should be possible to locate
some generic 40-pin cables, which should work (old IDE cables should work,
but not the new ones, which have a key that will prevent the connectors from
going in, in this application).
Also, it should not to be too hard to whip up some: the connectors and the
flat cable are pretty easy to find - although not the ground-plane backed
kind - do anyone know of a source for that? Anyway, the regular kind of flat
cable ought to work well enough for debugging.
