Well, the idea is that the console or diagnostic processor
is WAY simpler than the mainframe CPU. So, if the console
computer dies, you can troubleshoot it and be sure it is
running in just a few minutes, and then get on to the real
problem.
The VAX 11/780 had an LSI-11 with a floppy controller and an
interface board to the VAX, so I think it was down to 3
boards or something.
