It's a PDP-11. It's not Q-bus, nor Unibus.

Huh? Are you saying that you plan on running the front-end as a regular
PDP-11? It's quite a non-standard configuration as far as PDP-11s go.

2.11 will not boot on an HSC. It's quite a special environment, and the
only mass-storage that the PDP-11 have itself is the RX50 floppies.
