Neat! Thanks!

Those would be great - I hope they include enough detail to explain how the
ENABLE hooked up the various busses, cache, etc! I live in hope that someone
finds a manual, because that may be the only way these questions get answered.

Also, I wonder if the product called the "ENABLE/34" (per various brochures,
Muuss' email, etc) and the "ENABLE" we ran in the 11/45 were actually the same
thing, and they had just changed the name, perhaps because people might have
assumed, from the "ENABLE/34" name, that it was only for /34's, when in fact
it could run in any UNIBUS machine? The name change may have opened up a
bigger market for them. Anyway, another mystery about these things!
