Extremely rare calculator from the 70s. 

Untested as the original battery pack is not working and there is no power adapter. Battery compartment is clean as can be seen from photos. 

Some marks, rubs and slight scratches from previous owner. Discolored strip on right side is likely from a label. We have not cleaned any part of this calculator.  We wanted to leave that to an expert.  Please refer to photos. They are of your actual items.

Sold AS-IS, no returns due to no testing. This is being sold as a collectible calculator and I offer no guarantees of its proper operations. 

The Owner’s Handbook is included which is also extremely hard to find. This includes all the instructions on how to use the calculator. It shows some wear to covers, corners and pages and has a few marks.  

This was owned by a professor who was downsizing to move.
