[cctalk] Dec pdp 11 ultrix

Hello, Been a while since i last posted here. I have a few pdp 11/34 systems. The drives i am using are RL02 drives. Is it possible to install Ultrix on a 34? I have been testing out Ultrix in the simh emulator. I see during the install the 34 mentioned as a recognized cpu type, but later in the install the system hangs. This hang does not occur if i emulate a later cpu system like the 11/83. Not sure if ultrix can be installed due to the memory limitation, if not, rsx will be my second choice. Hoping to have some real hardware running soon! Thanks, Devin D.
