You could net-boot an 11/23+ over various flavors of
sync serial boards.
The problem is that most people don't have the sync modem eliminators, etc.,
to feed such beasts.

You could also use the basic serial (DL/DLV) ports for this too. MOP
however only loads a single image but if you pick the right one and it's
aware of it's IO it can do more than that.
I used to MOPload a PDT11/130 as a hypersmart tube and also back when to
do same for falcon cards (t-11 on SBC).
The alternate is the host can run a TU58 emulator and then stuff like XXDP
and Rt-11 can run over a serial port line as if it were a disk. I
remember seeing a unix tu58 emulator out there though the task is not
that complex.
