hp50codes

This is a personal repository for some small programs for my HP50g. In loving memory of those from my college years I lost on an old SD card.

The programs are written in UserRPL. Because RPN rocks.

List

nuclear

Includes some variations of the semi-empirical mass formula, some constants and related stuff.

astcoor

Includes some formulae for astronomical coordinate conversion. Angles are (supposed to be) picked from the correspoding quadrant. Calculator must be set in degrees for some of them to work. Order convention is the same as in the textbook I used.

markov and cmarkov

Some programs related to discrete-time Markov chains and continuous time Markov chains. Check Aid variable for help.

Notes on connectivity

Install ckermit

sudo pacman -S ckermit

Physically connect with usb cable and check with dmesg | tail. Now sudo ckermit -l /dev/ttyUSB0 or something similar. In kermit you should first

set carrier-watch off
robust

This can also be set in a .kermrc file.

• To send a file to the calculator LSHIFT+LEFT PAD to put it in server mode and then send foo.
• To receive from the calculator set the computer in server mode by running server and then send the file with the SEND command or from the APPS menu.
