I have just checked in some code to spin up the other CPUs on a
multiprocessor VAX 8200 system, It doesn't do so much things, though.
It cannot do printf's from the slave CPUs yet. A VAX CPU has an internal
register that is the console output that is only accessible on the local
CPU, so printf on a slave CPU writes the output out on the slave CPU
console (which is not what is wished). I don't know yet how this shall
Anyway, just for fun, the boot text:
