an off-the-rack DEC synchronous serial interface like a DU11?
Sorry, no idea. I have only studied PDP-10 interfaces.
Anyway, you don't want to use VDH.
If imp11a.c is beoynd repair, I'd say go with the ACC interface. There
is documentation and a working emulator already exists, albeit for a
PDP-10.
