Model DM41X


The DM41X, another member of our flagship line-up of RPN calculators, is a faithful recreation of the software environment of the HP-41CX, one of the most versatile calculators ever created and the first alphanumerical calculator, in a modern hardware architecture. Easily share or back up your programs or your entire DM41X environment and use hundreds of existing, professionally developed software applications with this rugged calculator sporting a stainless steel case and a Gorilla Glass screen.

Like all SwissMicros calculators, the DM41X uses the efficient and time-tested RPN logic.
