RE: Exploring the beauty of retro electronics (Gallery)
From time to time, I like to make calculator designs.
Attached to this post is my design for a entry level RPN calculator, named the Key Coder 34RPN. Features: 20 Memory Registers (00-19) 20 Program Areas (00-19), each with 100 steps (00-99) Modes leads to angle measure and display settings Stats allow for linear regression The program edit mode shows the key code and the function, with the up and down arrows taking the place of SST and BST, respectively. Subroutines are ran by having the RUN command in the program during editing (implied return in the end). |
