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
