Intergraph shipped multi-processor Pentium workstations in 1994 and 1995
(the TD-4 at least); the fastest Pentium available in 1995 was the 133MHz
P54CS. The March 1995 issue of Byte has a review of the Intergraph TD-4, and
http://www.ceu-inc.com/intergr_6d.html mentions that the 28" monitor was
intended to be used with the TD or TDZ workstations.

Back then of course the fastest workstations used Alphas...
