Maybe you're thinking of the RH70, the MASSBUS <-> PDP-11/70 memory bus
interface? But there was also the RH11, a MASSBUS <-> UNIBUS interface, which
supported all the same devices (RP04-6, etc) as the RH70, but plugged into a
UNIBUS. (The two were programming-wise almost identical, the RH70 had an extra
register for the extended memory address bits, plus a 'CSR3'.)
But I was speaking of the RP11, a UNIBUS interface for the RP03 (different
beast from the RH11, although very similar).
