What never was clear to me was if you actually could access the serial card
or not from the console. I.e. did it respond when addressing it? If it did
respond I would check that there were correct power supplied to the 1488
driver.

The M9312 does yes have the terminators installed.
I have not been able to activate the M9312 with the DD11C backplane
"behind" the newly-installed core and DD11B backplanes. I don't know if I
fried it somehow recently. It was working before. The M9312 is installed
on the 4th slot in the DD11C with a NPG card below it. It is also possible
that instead I am not communicating with the cards in the back of the bus.
Typically I toggle and run from address 165144 from the front panel, then
use the console program from a terminal to go from there. Since my recent
shenanigans with the backplanes the console program does not appear to load
nor run.
When I load the address 165144 I see the correct address on the front
panel. RUN BUS PROC CONSOLE are all lit. When I enable and start the
system the address lights go out except 020 (2nd to last light). The RUN
BUS PROC CONSOLE stay lit.
When I examine
165144 177570
165146 177570
165150 177570
165152 177570
etc
I don't know the status of my M7856 card. There are things I can try but
first I believe I should test to see if I am "pinging" to the DD11C at
all. I also need to check power output levels and adjust.
I am thinking also test the MOS RAM from the DD11C by itself to see what
that tells me. I know to address the RAM somewhere other than the 16K
space from 000.
