Attached: 2 images Got this TI Datamath 2500B up and running last night. Just needed a good clean in the battery compartment, and maybe a bit of deoxit on the key contacts. Just missing the brand plate ID badge above the keyboard :( #Calculators #VintageCalculators #Retro #RetroTech #TexasInstruments
