I guess that you're going to be pretty upset when you find out that a well
designed micro (say, a 68040 system) or two can give you more computing power
than an 11/780 at far, far less cost.
Heck, even an 80386 compares well until it hits a context switch. The
architecture is so ugly as to be sinful, though.

An 80386 in protected mode using the built-in task-switching mechanism takes
about 250 clocks (10 microseconds for a 386/25) to do a complete task switch.
Not bad considering the amount of state which is stored and loaded (120
bytes) and all of the validity checks which are performed.
