12	Initial implementation of a Vector Graphic HD/FD Disk Controller with Wishbone interface. See the PDF in /doc for more information about this controller. For now, the storage is implemented in FLASH memory, which is read-only to the controller. Also, the controller does not check (CRC) the disk sector data, like the original does. Instead, it inserts 00's where the CRC goes, to simulate a correctly checked CRC. I am able to boot CP/M 2.2 using this controller, with the vgboot.mcs image programmed into FLASH. See the diskimage/ directory.	hharte	5694d 04h	/
