go01
- Commercial HP01 emulator for android.for ease of use, displayed as a classic look alike.
- quartz synced with android time, so good accuracy.
- automatic save and load of state.
- alarm beep only when time displayed.
- stopwatch beep at zero only when displayed.
- dynamic calculation supported
- no timeout on displayed information (battery is no more a concern ...)
Not an exact replica of the HP 01, the rom is taken from a preproduction patent # 4158285: ie there is no % function on this emulation.
It is best to get a manual to use this emulation.
A better display as a watch will follow

Some technical details:
- re type the rom listing from patent 4158285
- make a cricket assembler
- check proof the rom
- use patent 4158285 to emulate cpu and display module (more complicated than a classic calculator)
- try to fully understand the internal format to have a good accuracy on time, stopwatch and alarm
- make a 'nice' calculator like skin to debug it
