Yes of course bad choice of words. The console ROM socket is separate from
the 4 bootstrap ROM sockets.

1) the console rom does not go in any of the 4
bootstrap slots, these
should be empty for now. There is a special console rom slot.
Just to clarify, by "slot", you don't mean 'backplane slot', you
mean
'socket
(on the card)', right?
Also, note that the console/diagnostic ROM is a different size (bit-wise;
I'm
not sure about the physical package) from the bootstrap ROMs.
Yes but if it's on and when you power up the system no @ sign appears at
the terminal that says it's not autostarting the console. At least knowing
what to expect (off or on) is what's important.
As I said, the 11/04 has specific wire jumper settings. Such as W8. These
must be correct for the CPU, the UNIBUS must be in a non DC LO AC LO, etc.
I went through all this with my 11/40 (not 04) and it was a great way to
learn about and diagnose the machine function.

6) possibly the only switch to worry about now is
the power on auto
jump to console switch.
I'd leave that, too, until we get the software console to run when started
manually - at the moment, the ROM's not working, so that switch is
irrelevant.
