Unix and C spread wildfire-like after most of the 20 years (until
sometime around 1997, I could say I'd been around computers more than
twice as long as C had existed outside the lab).
In the 1958 or so timeframe, there was a rack of gear at the back of
MIT's computation Center (which housed an IBM 704). This rack was
being built to interface a teletype (Model 28) to the 704. Almost as
soon as it was working a little, IBM replaced the 704 with a 709...the
rack instantly became useless, since the IO structure of the new
machine was entirely different.
The replacement was built and working a little, when the 709 walked out
the door to be replaced by a 7090. This only took a little tweaking
here and there (mostly timing issues). [Later, the 7090 was replaced
by a 7094, and then a 7094-II.] The careful observer here will recall
that Multics was eventually built on GE equipment.
Mid 50s to mid 70s...the era of IBM and the Seven Dwarfs (fewer than 7
by the end of that time through mergers and departures). Every Dwarf
had better hardware or better software...some including Burroughs had
better both. IBM had sales (oops...leases of bundled
hardware/software, until the Judge told them they couldn't do only

NCR's John Patterson fired Tom Watson Sr (his top marketing guy in
today's terms) for not being aggressive enough. ;-) Of course, that
was the era in which a Western saloonkeeper who didn't buy a register
from the friendly NCR salesman was fairly likely to suffer a broken leg
shortly after. Amazing coincidence.
