just for comparison, to see how far we've come (alternatively, how
far the h/w guys have come relative to s/w!):

a -10 looks to have been about 5 times the cost of an -11, and with a
quick detour through:
a 40k PDP-11 in 1971 USD is on the order of a couple hundred K 2010
USD, which would put the PDP-10's at roughly 1M current USD.
