The HP-41C series are programmable, expandable, continuous memory handheld RPN calculators made by Hewlett-Packard from 1979 to 1990. The original model, HP-41C, was the first of its kind to offer alphanumeric display capabilities. Later came the HP-41CV, with 4 times the memory space. Would you like to tell us about a lower price?
What do you think about the HP-41C mitteilungskarte?
Machine-readable “HP-41C Mitteilungskarte” addressed to “Hewlett-Packard SA” Meyrin/Geneva, Switzerland (German). Pretty good. No scratches on the back, keys feel a bit worn from extensive use, front dirty (seems someone glued a keyboard overlay to the unit.)
Where can I find a book about the HP-41?
HPCC members can find ordering details and a full book list in the Memberpack. A very detailed book (sometimes called the HP-41 encyclopaedia!) about the HP-41 handheld calculator/computer, still popular in some applications. £20, postage in the UK & Europe £4. Few remaining.
Can the hp-41c/cv have extended memory?
To execute a program in extended memory it must first be copied to regular internal memory. The HP-82181A “X-memory” module increased the extended memory space by 238 registers (1666 bytes). Apparently, only two such modules could be installed. Presumably, X-memory modules could not be installed in the HP-41C/CV.
