The HELLO program is a very simple program that prints "Hello World"
to the serial port of the 8051.  When you can successfully build and
run this program, you have used the entire toolset including:

The uVision integrated development environment
The C51 compiler
The BL51 linker
and the dScope simulator/debugger.

The HELLO project is available in two versions:
  HELLO.PRJ   uses the dScope Simulator for testing

  MHELLO.PRJ  uses a Monitor-51 based environment for testing
              and runs on a target board like the MCB517 board
