*Many 'vintage' calculators utilized proprietary rechargeable batteries and power supply / chargers. The original batteries likely included will be past their usable life and would need to be replaced to allow calculator to be used. The unit may or may not come with the original power supply / charger. We would have used our 'bench power supply' to test, but to actually use the calculator, new batteries would need to be sourced to replace the originals, as well as a power supply, or the battery compartment / connectors would need to be modified for a standard battery compliment such as a 9-Volt. Depending on the internal design of the calculator we may offer this as an 'upgrade' for additional charges.
