Pick up a common as dirt M7555 RQDX3. If you don't have a BA23 with the built in distribution board for the M7555 RQDX3, then pick up an M9058 distribution board to break out the signals from the M7555 RQDX3. For example, this one which is incorrectly listed as an M9056: https://www.ebay.com/itm/VINTAGE-DEC-Digital-Equipment-M9056-5016673-01B1-RQDX-Signal-Dist-Card-Board/153396701812
