<This evening I accidentally aquired a PDP-11/23 (model # 11E23-FE). It
<has RD-52A hard disk and dual floppies like the ones on a Rainbow.

sounds like a BA23 with a PDP-11/23 in it. There are many varients of the
11/23 cpu and you need a handle number and boot page info.

<What can I do with it? It does boot and is running RT11 with 512k of ram.

First off it's a computer, you can do whatever computers do.
More ram? By PDP-11 standard 512k is quite enough to be very useful and
even a large system. More memory is in the form of boards assuming the is
space in the backplane for it.

<It appears to have a fault. It often runs for just a few minutes then
<drops to a _at_ prompt and starts spitting out strings of ? marks endlessly.
<Is this a failure anyone is familiar with? How can I tack more ram on it?

May be a problem with the terminal not the PDP-11. Some terminal emulators
if hit with the wrong stuff will spew crap. The PDP-11 you have likely
has halt on BREAK enabled.

<The machine is is fairly good condition and appears complete. --

While you supplied only a cursory description, it sounds like a nice
machine.
