I don't think it was long after HPIB was introduced that the first
corresponding IEEE standard was issued. I think Tek adopted it
pretty soon. Things were very awkward before HPIB, with GPIO
interfaces, BCD interfaces, instrument-to-parallel printer interfaces
hacked into GPIO interfaces at the controller side... ugly, ugly.

Let's see: It was announced in the October '72 issue of the
HP journal, and immediately submitted to IEC. It was approved by IEC
as a standard at the end of '75, I believe, after some revisions
and signal name changes; I think IEEE 488 is from 1978,
and 488.1 was issued in 1987. But by the end of the 70's
it was definitely a multi-vendor standard for instrumentation.
