v1.1

Emulation of the z80pack Intel 8080 core on Arduino Nano.

After memory optimization we have the following machine now:

8080 CPU with ca. 0.80 MHz clock frequency
UART for serial communication
2 KB ROM for programm code @ 0000H - 07FFH
1 KB RAM for data @ 0800H - 0BFFH

This machine now is good enough for running Li-Chen Wang's famous TINY BASIC, source included as example.
