2012-02-09 - Split character rom out to separate header file, with upper 128 entries
as rotated copies of the first 128 entries. -- AMR
29-12-2006 - created
30-12-2006 - improved and simplified
-- JB --
2008-10-04 - ARM version
2008-10-26 - added cpu and floppy configuration functions
2008-12-31 - added enable HDD command
2009-02-03 - full keyboard support
2009-06-23 - hires OSD display
2009-08-23 - adapted ConfigIDE() - support for 2 hardfiles
