Thanks very much, everyone, for the detailed answers. I suspect that, due to the huge performance gain I seem to get using NQC (in one observable area: touch sensor response time using two touch sensors on two separate ports), that the RCX Code (...) (25 years ago, 6-Oct-00, to lugnet.robotics)

Hello listers, Once again Lego has made a product that is without Mac support. I have tried all the Logitec drivers, but the camera must be a model without mac support. Have any of You found a solution for getting it to work ? Regards Mikkel --- (25 years ago, 6-Oct-00, to lugnet.robotics)
