Today I found an interesting article that compares mechanical adding machine with software calculators. I definitly recommend it for all of you adding machine users, who are not sure if a software calculator is the way to go, especially in finanical terms.
" Conclusion:

Migrating the adding machine functionality to electronic adding machine software, like DeskCalc, makes excellent business sense both from cost and environmental perspectives. I think it's time the mechanical paper tape dinosaurs faded into the same sunset where pencil and paper spreadsheets disappeared almost 30 years ago."

Subsequently, the detection of the next value, results etc. takes place.
