Well..one can't overlook the fact that regardless of the beauty of the
architecture, there were implimentation issues with the early 32000
processors. The errata sheets were a mile long. The 32332 & 32532 were
much better, bugwise & performance wise, but still had numerous issues.
There are some interesting workarounds in the GCC code generator. These
issues contributed significantly to the death of the line.

Encore Multimax, Sequent Balance, some nifty Tektronix workstations,
ICM3216, PC532, Heurikon VME532, many other more or less obscure boxen.
