Installing and running other OS than RT11 and XXDP (with TU58 emu) or BSD (with Vtserver)

As I told in a previous message, I was success installing RT11 v5.3 in one ESDI drive managed with one Dilog DQ696 (treated as a DU drive) in one PDP11 where I boot with one copy of this OS managed with TU58EM (TU58 emulator) I shall try in a while to install BSD2.11 with Vtserver, and to start XXDP But I should like to ask to ask everybody insterested about this question: Can I install other OS in the PDP11 using these pieces of software (Vtserver and TU58em) ? I was thinking in other versions of Unix previous to BSD2.11, or other OS as RSTS, IAS, RSX or DSM. By the way... Is this one (DSM-11) available in some form ? I know of one copy from one member of this list which was available some years ago but this is lost actually as far as I know. Regards Sergio
