Another production unit that shipped with lots of
wire-wrap on board was
the IBM 3803 tape controller. E.g. from Pat's collection:

The central computer (Hughes H5118ME) of the AN/FYQ-93 air defense
system had a slightly larger backplane, all wire-wrapped. It didn't
generally cause problems, unless someone was fooling around in the back.
It took us 5 days to track down a connection problem on the backplane
once, eventually doing point-to-point continuity checks.
