I've taken a quick look at implementing a similar BBC device, but failing to get the expected results on some commands:
06H CHECK_EXIST - must return last data EOR 255.
15H SET_USB_MODE - sending 06H and 07H seems to want 0x51 (Operation successful) returned.
16H ? - expecting 0x15 returned.
Looks like I need to do some research to implement these correctly.


BBC Model B, ATPL Sidewise, Acorn Speech, 2xWatford Floppy Drives, AMX Mouse, Viglen case, etc.
