If you had correctly read my reply, I did say that the driver software is not up to it, and that I also stated the reason why: the driver software relies on the TI-85 being at it's usual speed since it slows down things, and that slow-down will come out wrong on a turboed. If that doesn't suggest that new driver software would fix it, then I should have elaborated a bit. -- -R.Zwitserloot@BTInternet.com
