hardware notes:
- Mostek MK3870 MCU, 2KB internal ROM
- 12 digits 7seg VFD panel
- MC1455P(555 timer) + bunch of discrete components for sound, see schematic:

- MC1455P(555 timer) + bunch of discrete components for sound
TODO:
- sound pitch is wrong, standard beep should be highpitched
- MCU frequency was measured approx 2.1MHz on its XTL2 pin, but considering that
the MK3870 has an internal /2 divider, this is way too slow when compared to
video references of the game
