That's wrong. We run 2.9BSD on our 11/34, initially on two RL01 disks, 
now on one RL01 (as boot and swap device) and one RA80 (there is a 
third-party MSCP driver for 2.9BSD). I need to upgrade the machine with a 
cache and FPP board as time permits (I have the boards lying around 
somewhere). I could add a DEUNA, too, but it wouldn't work with 2.9BSD on 
this machine (I think the IP stack needs separate I/D and more memory).
