Can any of you guys verify one way or the other what that device with the 
tubes is that Dave is referring to in my group here?

Feel free to stop on by if you like.   :-)

I just added some photos in the Photos section of some really old
computer hardware.  These are photos I've taken from my personal
collection.

One is what I've been told is the peripheral I/O register for an
IBM 704 computer (Note the vacuum tubes!).

Another is a core storage (memory) plane from an IBM System/360,
most likely either a model 60 or 65.  This particular core plane
was defective, and has been cut out, so it's missing the connection
fingers on the sides of the plane.

The remaining two are a really old computing device.  ;-)
