"... DEC started to ship all its products by truck. Twelve-foot trucks. DEC learned a lot more at a well-known bridge on Route 62 in Hudson, Massachusetts. An eleven-foot bridge. (This is where DEC made its first drop shipment.) The PDP-6 that made this unfortunate journey was already some months late for the University of Pennsylvania. DEC, not having its own van at the time, had rented some space in a moving van filled with household goods. The PDP-6 was in the back of the van, and it appears that the furniture successfully cushioned the impact of the computer. They did have to shovel the remains out of the truck afterwards, however. (The PDP-6 was able to be repaired in a couple of more months.)" [PH1984]

from "The History of TOPS, or Life in the Fast AC's" session at the Spring, 1984, DECUS Symposium in Cincinnati, Ohio.

Private communication from Peter:

"When I joined DEC [from LNS] in '68, the PDP-10 had just started shipping. Most of the history recounted in that talk came from my own memories and from hearing stories from people like Alan Kotok or Tom Hastings on our regular dinners out at Chez Claude's or the local Chinese restaurant."

"The document seems to relates to core memory royalties."
