Civil Defense Museum

Looking through some old accumulated pics from over the years.

Some pics of the 711 MK III. The case bottom has 3 1/4 inch holes drilled through so I guess it must have been mounted to a wall at one time.

I filled with epoxy and mixed some testors yellow enamel with white to match the case to couch up and paint over the filled holes.

There was some pretty heavy surface rust in the case bottom below the schematic. I was able to remove it with evap o rust but couldn't risk messing up the schematic so I left that edge of rust along there alone.

I think the connectors must be nickel plated because I believe they are tarnished. I started cleaning them with a pink pearl eraser which does a good job.

I get less than 1 ohm of resistance when checking the cable with a multimeter so maybe the cable is good.

I'll hook it up after I get the connectors cleaned and see what it does.
