Porteus

Free42 is a HP-42S RPN scientific calculator simulator.

The HP-42S was manufactured from 1988 until 1995 by Hewlett-Packard.

The Free42 program is a complete rewrite and contains no HP code whatsoever.
Has a realistic calculator display, and looks great!

The porteus module for free42 3.0.2 (3.1MB download) is for Porteus x86_64 and may be downloaded via this link:

Note, that free42 saves some small files in a free42 folder located at:
/home/guest/.local/share
So if you try free42 and decide it's not for you, you should delete the free42 folder (although it will do no harm if you don't delete it).

Hi, i've seen source-code for the HP-48 mentioned recently, i think i saved it on disk just in case... There happens to be some old .E48 image-file dating back to about 15 years ago and the calculator was probably a relic itself already, as i purchased it around 1993 - and it's still on my desk today, fully functional. Built to go in space! Very stimulating in days when i could afford the long hours. It's reminescent of an era when still recording software on audio cassettes... Hoping we all got the scene in mind! But i can't begin to shop around for another, this one is beyond my everyday needs and i'm no Ti fan anyway.

So you can be shure i plan to evaluate this virtual HP-42S calculator as that's still pretty much what i need to keep around. Thanks for making the post!!
