-ARDUINO PARALLEL TERMINAL DEPLOYER
-This software sends a compiled Z80 binary files to Pat80 monitor via an arduino
-with flashed arduino_terminal firmware.
-
-USAGE:
-Connect the arduino to a Pat80 I/O port.
-Flash /arduino/arduino_terminal firmware into the Arduino.
-Connect the Arduino to a PC via USB and power on Pat80
-In the Pat80 Memory Monitor select I for IMMEDIATE LOAD
-Run this program providing the Arduino USB port and a Z80 binary file
-The code contained will be copied in Pat80's memory and executed immediately.
