Additions in the USB handling
-	SLEEP command will switch entirely the power to the USB module in order to minimise the power consumption.
	USB will be reinitialised upon a wakeup event.

Additions in the SDCARD functionality
-	Support for up to 4 SD cards.
-	The command OPTION SDCARD has an extended format now:
	Option SDCARDx CS-pin [, CD-pin [,WP pin]]
	where "x" can be 1, 2, 3, 4
	In order to maintain compatibility with the original release of MMBasic, "OPTION SDCARD" is equivalent to "OPTION SDCARD1"
-	command DRIVE syntax: DRIVE drive$ where drive$ can be "A" (currently reserved for future internal drive), "B", "C", "D", "E"
  default startup drive is B
-	RO varialble MM.DRIVE syntax: "MM.Drive" returns 0 for A:, 1 for B:, etc.

Additional support up to 4 external SD cards via a bi-directional 2:4 multiplexer. An example of such use is in the ELLO 2M system
-	OPTION SDCARD allows now a further extended syntax
	Option SDCARDx [MUXn, drv0-pin, drv1-pin,] CS-pin [, CD-pin [,WP pin]]
	where
	"x" is a SD card number (1..4)
	"n" is the multiplexer output number (0..3)
	"drv0" and "drv1" are the two pins to drive the multiplexer
- The way a multiplexer is supported is universal and can be applied in a number of different configurations
  a single example of the mentioned ELLO 2M system uses the following configuration for its multiplexer:
  OPTION SDCARD1 MUX0, 51, 46, 12, 33
  OPTION SDCARD2 MUX1, 51, 46, 12, 33
  OPTION SDCARD3 MUX2, 51, 46, 12, 33
  OPTION SDCARD4 MUX3, 51, 46, 12, 33
-	The configutation for use of multiplexer are optional and depend on the presence of MUX in the OPTION parameters

Full 8-bit ASCII character set support
-	A string which starts with an extended ASCII code must be enclosed in double quotes. Example: ""µmite""

Additions to in-shell firmware update and a new MMBasic command FWUPDATE
- Uses Windows update software to update the firmware via USB

Additions to include support for Winstar LCD panels with built-in SSD1963 controller
-	support for panels WF57Q, WF70Q, WF80Q, and WF102Q
- new OPTION LCDPANEL SSD1963_7W to support Winstar WFQ panels

Additional 10x20 console font #97 with full set of printable ISO-8859-15 characters plus pseudographic and math characters
