>If the sticker says 11C23 then it's most likely a 11/23, yes.

The only way to tell for sure though is to check the number on the handle
of the CPU board.  Just because the chassis started out as a /23 doesn't
mean it's a /23 (after all my PDP-11/73 says on the chassis it's a MicroVAX
II).

Once you have the number from the handle, check the following list.

to identify the rest of your boards.

What is port-pdp10?  Is there an attempt to port NetBSD to the PDP-10?
