	The CoCoDEV has a high density female DB15 connector for VGA video output. RGB video signals as well as horizontal and vertical synchronization signals are all available on the connector. The video should drive any modern monitor designed for analog VGA. The VDG generates the video with a 25 MHz dot clock with 640 pixels of horizontal resolution and 480 lines of vertical resolution. Currently, the only mode of operation is a semi-graphics text mode using a eight pixel (horizontal) by sixteen pixel (vertical) character block. This allows for an addressable display using eighty columns and 30 rows. The video system has a color density of 8 bits configured in the common 3-3-2 (RGB) format. In theory, this allows up to 256 colors on screen at once.		The CoCoDEV has a high density female DB15 connector for VGA video output.

	=== PUTFLASH ===		=== PUTFLASH ===
		+
		+	Putflash is a utility used to write data to the flash memory chip on
		+	CoCoDEV. The chip is a Winbond W25Q32 device. The minimum chunk of flash
		+	memory which can be erased is 4 kilobytes. Therefore, the putflash utility
		+	works with blocks of 4k. The usage syntax is:
		+
		+	putflash <filename> <start blk>
		+	Where <filename>. is the OS9 path to the file where the data
		+	will come from and <start blk> is the starting block number
		+	(in hex) in flash.
		+	Example: putflash test.bin 0A
		+
		+	Putflash may be used to flash the stock Tandy BASIC ROMs as well as the PATCH
		+	and BOOT files to the onboard flash memory.
