Sharp Memorizer 60

We know very little about this machine, made by Sharp, that says "Memorizer 60" on the front, and Model CSA-12 on the back plate.

The machine has a large connector on a many-conductor cable, two Nixie tubes that show numbers when it's plugged in, a number of indicator lights, and but a few buttons and switches.

Sharp made a variety of transistorized calculators in the early seventies under the name "Compet." For example, one such machine is the Sharp Compet CS20. You'll see the similarity in design.

Dick thinks this must be a keystroke memorizer, that is, an external programmer, for the Sharp Compet series of calculators.

Has anyone seen one of these before? Any other theories? Please email Dick if you have any information or good theories.
