Emulator for Hewlett-Packard series 9800 calculators. The complete hardware of the HP9810A, HP9820A, HP9821A, and HP9830A calculators of the early 70s is emulated. Keyboard, display, and many peripheral devices are visualized and full functional.
Very good and detailed emulator. Emulates pretty much all available external devices and expansions. Useful option to configure keyboard keys. Sounds are also nice addition, even when they are not important at all ;-) The only problem is lack of detailed documentation. I still do not really know how to operate tape drive (i am unable to read programs, i am not even sure if they are being written) and also i have no idea how to operate statistics expansion module as there are no informations about its functions (mathematics and custom functions modules have such informations).
