A visual HP-45 calculator emulator written in Python #Emulation #Python @sarahkmarr
Sarah K. Marr has written the HP-1973, an HP-45 (or HP-35 / HP-80) calculator emulator.
I love the HP-45 calculator. It’s beautiful on the outside, but I wanted to show people that it’s beautiful on the inside, too. So, as a coding and retrocomputing challenge I decided to rewrite an earlier, terminal-based simulator of mine in Python (but with standalone executables), with a GUI. As with all such ‘just a few days on this’ projects it spiralled out of control, and the result is HP-1973.
It not only runs (included) ROM code from the HP-45, but also the HP-35 and the HP-80. You can select which calculator you wish to use when the application starts, and also have the option to choose between multiple ROM versions for a given calculator (with warnings if a ROM is known to contain bugs). In total, six calculator-ROM variations are included.
There is a mac and Windows standalone application as well as the Python source for use with existing Python 3.10.10+ environment (macOS/Windows/Linux/FreeBSD).

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
