I've got a PDP 11/34 I've never opened

Is there a catch or lock screw on this unit?
Mine (and we may be learning, is not be a proper configuration) does not
have any release or catch to allow the CPU to slide out. I just grab it
and start pulling and it slides out-- although it does not slide easily.
That could be due to old, stiffened lubricant on the slides.
Might be a non-standard slide, or a defective lock.
BUT! make sure you pull out the front foot at the
bottom of the rack to keep
the whole rack from tipping forward if you do get the CPU to slide out.
The CPU is a heavy beast and the rack WILL tip forward once the CPU is
out far enough.
That's why H960 cabinets have optional front stabilizer feet.
RL's will flip it too. And let's not even go into RA's. :-)
