Excelent condition modul / fair price

This rare and "unclonable" modul is a "must" for every HP-41C & HP41-CV owner.
Many ROMs (Navigation,..) and applications (Data aquisition,..) relay in its functionality.
The 41CX have it already integrated. The advantage is having another slot free, but the "con" is that you can't take it away and place on another 41. I'm happy.
