Multi Calculator Kit

[teenix]

Hi all,

The MultiCalc has been updated again.

I have managed to add the HP-46 printing calculator, which means it is now capable of emulating 27 different models.

The HP-46 functionality is almost identical to the HP-45 and therefore I was able to use the microcode from that model. There are a couple of differences with the HP46 having two additional Clear functions and of course the printer interface.

To make it work, the PIC code continually monitors the running HP microcode and will determine what needs to be printed. If printer output is required, the PIC will send the printer commands to the PC via the USB port and the emulator program will print the data in the same font as the original mechanical printer from the HP-46. Example attached.

The HP-46 also has print commands for displaying the stack and memory etc. and these extra functions have been assigned to some shifted number keys.

The top switch for my board controls the power and also turns the printer on or off.

Haralds controller has also been updated and can also simulate the HP-46, and has a new menu item for printer on/off.

HP-46 keyboard overlays are available for both boards in the download.

Update available from http://www.teenix.org

cheers
