Correct.

You need to check out if all of these really works in an 11/84. I don't 
think they all do. Some had hardware bugs that meant they only work in 
the 11/83 configuration.

Yes.

Yes.

The bus grant goes into the middle slots. There are two models. One 
really small one, which is only one connector high. They should go into 
the fourth slot from the top if my memory serves me right. In this case, 
you also need to make sure the NPG lines are are connected. This is done 
by a DIP-switch block on the backplane. One switch per slot. It should 
be visible if you look down into the cage. The other bus grand card is 
two connectors high, and also carry the NPG line, in which case you 
don't need to worry about the DIP-switches.

Yes.

You only need one memory card, so it's not really neccesary to get two. 
Also, no grant in the slot where you have the TUK50. But I'm missing a 
grant in slot 6. :-)

Yes.

Yes.

No need, normally. The 11/8x and 11/9x cards have nice large boot proms 
with all kind of boot routines on them, including booting from TMSCP.

Yes.

That would help if you don't feel like starting to write your own code. 
But for test purposes, not needed at all.

If you're just interested in checking that the machine is working, skip 
the TUK50. Just make sure the unibus is "whole", and fire her up. The 
boot monitor of the 11/8x and 11/9x are real talkative, with lots of 
things that can be done without anything else, including running tests, 
and checking out the hardware.
