One of the OS's I run on my PDP-11/34C is BSD 2.9. It does NOT require
separate I/D spaces. The following are supported by BSD 2.9: 
-----------------------------------------------------------------------
PDP-11/23, 24, 34, 34A, 40, 44, 45, 55, 60, or 70 CPU with at least 192
Kbytes of memory

Any of the following disks**:
DEC MASSBUS:	RM03, RM05, RP04, RP05, RP06 DEC
UNIBUS: RK05, RK06, RK07, RL01, RL02, RM02, RP03, RP04, RP05, RP06 AED
8000
UNIBUS:	AMPEX DM980 (emulating RP03) AED STORM-II AMPEX DM980
(emulating RM02) DIVA COMP V
MASSBUS: AMPEX 9300 EMULEX SC-21
UNIBUS:	AMPEX 9300, CDC 9766 (emulating RM05) EMULEX SC-11 or
SC-21 UNIBUS:	CDC 9762, AMPEX DM980

The tape drives supported are:
MASSBUS: TE16, TU45, TU77
UNIBUS: TE10, TE16, TS11, TU45, TU77 DATUM 15X20
UNIBUS: KENNEDY 9100 (emulating TE10) EMULEX TC-11
UNIBUS: KENNEDY 9100, 9300 (emulating TE10)

I run BSD 2.11 which DOES require separate I/D spaces on my 11/83
