Love this type of transaction. I as the seller took a lil less than I was originally asking, but totally worth it when the item goes where it is needed and wanted. Buyer paid quickly and all smiles all around.

HP 41CX Calculator & Card Reader + Math + Manuals Issue
09 Jun, 2017
the best calculator ever?
The HP-41C (of which the CV and CX models are impoved followups) is considered by some to be the pinnacle of programmable calculators. What sets it apart is the wide variety of expansion modules-- magnetic card reader/writer, infrared bar code reader, printer interfaces, ROM modules preloaded with application-specific programs, etc. It is one of the earliest calculators with alphanumeric support. About the only thing it doesn't have is a large enough display for graphical output. Thie HP-41C/CV/CX was sold at the time when personal computers were becoming popular and affordable, which ultimately led to the de-emphasis of further development of calculators at HP and other companies.
