Hardware Voyager Emulator

[agarza]

So Ive been working on a simple, easy to build hardware emulator for the Voyager series.

I have tested it with HP11, HP12, HP15 and HP16 ROMS. And they all works fine. (HP15 Self test does not work)

Approximately 4~5 times faster than the originals.

It is running on a single chip. A ATMEGA328 8 bit microcontroller @ 8MHz.

It has:
- a real time clock
- sound (only for keypress feedback)
- 192x64 lcd display
- Display Backlight
- Runs on a sigle CR2032 3V battery

Please check out the video and let me know what you think.
