Not quite; it does _mostly_ 'do its thing' over the UNIBUS, but there are
also two special lines carried across the DD11-P backplane to the CPU, 'Halt
Request'
Got the last replacement components I needed for my LA30 restore today,
and finished it up! Here's a short video of the LA30 connected as
console to my restored PDP-11/45:

The problem is it randomly does not turn the media unless I give it a
push to get it

My copy of of the V7 standalone stuff (which I got from the VTServer
directory) didn't include an RX driver. Where'd you manage to find one?

I am reviving an 11/34. Cards are:
Back/Fans [M8266] Front of machine where keypad is.
[M8265]
[M9312] [M7859]
[M7762]
[OPEN] [M7860]
[M7840]
Bus grant in third from front slot
[M9302]
I also have an 11/04 that I went and drug out. It is configured like this:
11/04:
AAA BBB CCC DDD EEE FFF
(Rear/Fans/Power Supply) 1 [M7263] (Front/Keypad/DC ON)
2 [M7847]
I added an M9302 in Slot9-AB and then moved the M7856 from the 11/34 to
Slot9-CDEF of the 11/04. I put a random M9312 in Slot3-AB I turned on the
11/04.
I have six ‘0’ digits. I push ctrl+hlt and the display shows 173066. Looks
like things are moving.
The ultimate goal is to hook this unit
Ahh, that M9203 in slot 9, positions A – B, sounds more familiar (or is it
M9302?)
The M7856 is often in slot 9 position C – F, when used as console.
Interesting, the 11/04 also has that M7840 installed. Could you pull that board
(uhmmm, you did), and have a look at the texts in the etch? The

This is the map of the machine:

AFAICR (…), the M7859 is sort of a UNIBUS device. The (front panel) console
only communicates with the M7859.
The M7859 writes/read to/from memory using the UNIBUS. Have a look at the
schematics of the console.
I cannot remember whether a demux for the displays is on the console PCB, or on

Yeah; you can use the G7273 as a 'crib', since it has the NPG jumper on it.
That jumper goes from CA1 to CB1:

That's for the 10-1/2" box; the 5-1/4" is different. Which is this?

I would _definitely_ start by pulling _all_ the cards you can, to get down to
the simplest possible configuration. Once that works, start adding things
back in, one at a time.
If that configuration doesn't work, first try
Folks,
The tn3270 support in Hercules emulates channel attached 3270's not bi-sync so
may not be a good source of info. On a local 3270 controller each screen has a
unique channel-controller-device address.
On a bi-sync device only the line going to the device, additional addressing is
