The tuner port is a serial port, but at TTL levels. In theory, you could make a stalk interface to plug into there and pretend to be enough of a tuner that the player would recognise it.

However, we're looking into how we can get more tuners made - probably by collecting pre-orders. Need to check this out futher though, so don't email us about it yet - we'll announce it if/when we know we can go ahead.
