The seeds of a minicomputer revolution were planted as early as 1960, with the introduction by Digital Equipment Corporation of the transistor-based PDP1 for technical computing by engineers and scientists. The PDP1 was succeeded by the PDP5, then the highly successful PDP8 in 1965 and the PDP11 in 1968 plus 1.

a pdp1 page (as opposed to pdp11):
Hunkeler Peter , KIUB 34 multics started about then. lots of early 545 tech sq folklore ... mostly about cp67 and vm370 ... in melinda's history paper but when multics (5th flr, 545 tech sq) didn't choose...
a history of computers
from above: 1-48 IBM makes it first computer 1952 IBM produces 701, designed by Nathaniel Rochester, first production line electronic stored program computer 1954 IBM's John Backus creates Fortran 1954 Gene Amdahl develops first operating system used on IBM 704 1957 Harlan Anderson and Ken Olson form DEC 1960 DEC builds PDP1, producing 50 machines
... snip ...
so based on earlier reference, they may have started building PDP1s in 1960 but possibly didn't begin shipping the 50 machines until 1961?
so a little more topic drift about the boston programming center on the 3rd flr of 545tech sq.
the cp67 group split off from the science center and took over the boston programming center on the 3rd floor (and subsequent growth and morphing into the vm370 group, the moved to old service bureau corp. building in burlington mall).
as previously mentioned
Jean Sammet was at the Boston Programming Center on the 3rd flr at the time ... but so was Nat Rochester.
