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

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

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
