That was SOP for DEC. Anytimg something needed to be produced outside
of the lab and it was projected as production it would get the full
treatment.

That and it threatend to take some of the 11/780s thunder. One forgets
the 11/70 was the supermini of the day and not too shabby for some
time after.

Not all though. The system known as Video was an 11/70 that was an 11/74
at another point in time.

That and the multiport memory boxes.
