What is My4TH-nfd?
------------------

My4TH-nfd is an alternative firmware for the white My4TH board. It is equivalent to
the original firmware, but it has no support for the Forth Deck. Instead, it includes
some extra features:

  - much faster program execution (min. 30% faster than the original My4TH ROM)
  - faster I2C bus (approx. 3x speed compared to the original My4TH ROM)
  - improved line editing at the command prompt (e.g. support for inserting characters)
  - improved built-in text editor

Note:
The My4TH-nfd ROM can also be used with the Forth Deck if an additional driver is
loaded from the EEPROM. Please read the readme file in the my4th-nfd directory for details.
