I do have a bunch of Unibus 3270/X.25 boards from a third party vendor.
ACC (Advanced Computer Communications)? If you can find it, the PDP-11 RJE product was released to DECUS I have it on fiche, but that would be tedious to reconstruct. I don't think the comms requirements were that onerous. I thought it worked with just a DU or DV11 single-line non-DMA synchronous controller. The original RJEs couldn't run over 9600 bps. Supporting multiple synchronous channels required the fancier hardware.
