I'd love to see it if something turns up, I didn't think anything like this
existed.  Of course anything ought to be possible if you download your own
T11 code, but if the layout of the on-board hardware is documented anywhere
I haven't seen it.  So I don't know how an outsider could write their own.

Hmm, actually I was talking about the RX33 in both cases (the difference
seems to be between the RQZX1 and RQDX3 controllers), but this might
explain *why* there's a difference (since the RQZX doesn't support RX50
drives, right?).
