Curiously enough, 11/782 and other MA780-based models were not the only
multiprocessor design based on the 11/780.
Some brave souls just took out the SBI terminator and hooked in a second KA780
CPU in its place, using the created dual-processor machine to develop what
appears to be the very fir

Uh. No, as far as I know/remember they 83x0 were not asymmetric in the

Hi,
VMS 5.0 introduced Symmetric MultiProcessing (SMP) and discontinued support for
the 782. This would have been in the late 1980s by which time DEC had released
"proper" multiprocessor VAX models.
VMS still has the concept of a "primary CPU" and I think there are still some
interrupt handler

Wasn't the VAX 11/782 and the Asymmetric model de-supported at some point
during the life of VMS?
I seem to remember hearing (at a DECUS Symposium?) that existing 11/782
customers would have to separate them into two 11/780's and then cluster them
to upgrade to the latest version of VMS.
