Accessories Pouch

Totally bad battery pack

Power supply (110V)

Manual: Your HP Financial Calculator: An Introduction To Financial Concepts And Problem Solving, Nov 1980
Condition For the most part the calculator is in excellent condition. However, the top right edge from the red display cover has broken off. I used some glue to attach it.
Repairs, Comments Was sold as defective but after I removed the corroded battery pack and cleaned the battery compartment it worked fine with a new battey pack!
I cut off the connector of the powr supply and made a special cable that can be used with an off-the-shelf DC power supply.
