Yep! depending on version you your really need sources. I have an 11/73
with RQDX3 and two RD52s and V7 running on a 10mb RL02 cart. Without
sources all of the other disks unless older RK05s are useless. Also
it doesn't use all the avalable ram. Fairly useless other than it's real
unix.

Also problematic.

Almost begs a new PD OS that is on the simple scale, buildable and
patterned after RT or OS/8. Porting CPM68 (c source) to PDP-11 may be
doable for a simple 64k memory (16bit). Porting C sources is not my
area of expertize.
