Multi Calculator Kit

[teenix]

Hi all,

I managed to squeeze in the HP-91 original microcode into the Multicalc.

As this model has an extra 7 buttons, some of the key mapping was changed slightly and all the number keys were assigned some of the shifted functions.

The 91 also has 2 switches with 3 positions each, so one mechanical switch is used for the printer mode and the Deg/Grd/Rad is selected from the keyboard menu. The printer interface also works with the USB port like the other models.

There were a lot of changes made, so I'm just doing some final testing and then I will upload the files. Those who have a kit already can update the software and it will be ready for use.

cheers

Tony
