-- History: June 2020 - Initial creation.
-- Mar 2021 - Updated to enable better compatibility with the Sharp MZ-800.
-- Mar 2021 - Many changes to cater for the MZ-800. The machine has different memory
-- modes and maps so extensive changes needed.
-- Apr 2021 - Removed the v2.1 frequency generator as 2.1 no longer supported. Fixed
-- issues with adding the MZ-800 using too many resources, made
-- compilation conditional.
