You are not even remotely in dangerous territory here.
For some perspective, think of a sofa with "feet", with two or three fat
people on it.

This
conversation has started to worry me about the PDP-11/23 system in my
daylight
basement/family room. It's the largest single room in our home,
and on the bottom of three floors. It is a wooden floor, with (large)
crawl space underneath.
The configuration is a PDP-11/23 in a BA23 chassis, 2 RL02 drives, and the
standard DEC rackmount cabinet (which is pretty heavy itself). The entire
cabinet has been placed on a 2 foot by 4 foot piece of half-inch plywood to
evenly distribute the load. It is located near one of the load-bearing
external walls of the home.
RL02 drives weigh 75 lbs by themselves. Does anyone have a rough guess on
what the total weight is for the system I described, and whether or not
this would be safe for residential basement wood flooring? I realize there
are a lot of factors - I'm just trying to get a wild guess before I start
getting panicked.
Thanks,
