I have four 8/e systems here (including an 8/m, I classify them as the
same because they mostly are) and I've swapped parts around a lot. They
were only "old" (meaning "passe'", not "antique") when I got them, so I
never really thought about them from an "original equipment" perspective.

the backplanes one was labeled I think 1970 and the other was a couple
years later. It also had one 3 digit processor card. It may have been
bought as a single backplane machine and upgrade or they had to replace
a bad backplane.
