Thanks for that information. Pretty cool. Lots of money...

No. The 86x0 machines have a built-in PDP-11 for the front end. This
PDP-11 has its own Q-bus inside the VAX, and on that sits a RLV12
controller, with the FE RL02 disk pack, on which all microcode,
diagnostics, tools, and the FE console handling software resides. (It is
actually a specially tailored RT-11 system.)
If anyone, anywhere, plans on running an 86x0, please contact me. Unless
you really know what you are doing, chances are that you will not manage
to get the machine running, or that you'll break it in short order.
Important things to know: The machine *really* needs 3-phase. And the
phases have to be ordered right. The blowers are 3-phase motors, and
they create a small storm behind the machine. The machine is all ECL,
and really need the cooling, or else it will break. The RL02 is critical
for operation of the machine. All the microcode is loaded at boot time
from the PDP-11 into the VAX.
The VAX have a battery back unit for RTC. Chances are that the batteries
have gone bad if the machine have been in storage. They are 12V lead
batteries. Without healthy batteries the machine will not start up.
There is a jumper you can install to get around this, but it's not
All that said, it is my favorite model of all time (although maybe a VAX
9000 would beat it, if I ever would have a chance to play with one...)
