You mean it isn't in the Sysgen manual? Strange.

Here goes:
     RC11 DC
     RF11 DF
     RS03/04 DS
     RK05 DK
     RK06/07 DM
     RL01/02 DL
     RP02/03 DP
     RM02/03/05/80, RP04/05/06/07 DB and DR
     MSCP DU

MSCP appeared fairly late, V8.0 I think but I don't remember exactly.

DB and DR both refer to Massbus moving head disks. Until V9.0, there
were somewhat odd rules about mixing them on a single controller; the
details should be in the book. Best rule for SIMH or E11 purposes is
NOT to mix "RM" and "RP" drives on a single RH11/RH70. If you want
both, put them on separate controllers. If you do that, then the RM
drives will be called DR, and the RP04... drives will be DB.
