The first (SMP) one that comes to mind is a VAX 8800
(I only have 1/2,
aka an 8700), or my VAXstation 3520/3540.
Of course, there were other non-SMP systems (like the
Dual VAX
(11/780)), and systems that had multiple CPUs but weren't really
dual-processor (DEC Rainbow).
The first that comes to mind is the PDP-10 Model 1055, a master-slave dual
processor, c. 1968. Then the 1077 and eventually the 1099, replaced by the
SMP systems, which could have anywhere from 2 to 5 CPUs (maximum # built,
theoretically up to 8).
There were dual-processor System/360 models in the 1960s, too.
