Your honour, I offer into evidence from
http://www.digital.se/foretagsinfo/mileston.htm :
"October 1990
<snippage>
Introduction of the applicationDEC 433MP system, Digital's most expandable
system for small and medium-sized businesses, which is based on the
popular SCO UNIX System V and the Intel 486 microprocessor."
And according to
http://www.intel.com/intel/museum/25anniv/hof/486.htm ,
the 80486 DX processor was introduced in 1989.
Of course, these babies weren't exactly in the consumer channel in 1989/90.
IIRC, I found a reference to the original purchase price of an appDEC 433MP
being $15,000 US.
Cheers,
Mark.
