That&#x27;s not really true at any level.  There were decent i386 SVR3 releases before 1990 and some very nice SVR4 releases soon after (particularly, Dell).  I deployed a lot of them as an alternative to workstations.  HP and DEC were <i>not</i> cheap in that timeframe, though you could argue they were more capable.  And while not a &quot;PC&quot;, a 64-bit desktop showed up in the form of the R4000 in 1991.
