I have heard that RCX 2.0 has more memory in it than RCX 1.0 . Could you use tools like RcxCC to check the amount of memory in your RCX 2.0? Cheers, Hao-yang Wang (24 years ago, 8-Mar-01, to lugnet.robotics)

I need to make a decision about purchasing Mindstorms kits for my sons school. We have decided to buy 5 or 6 RIS kits. The question is, should we buy 1.5 kits that I can get a hold of now or should we wait until fall to get the 2.0 kits? So far, I (...) (24 years ago, 9-Mar-01, to lugnet.robotics)

I'm sorry to say that I don't have anny suggestions, just some more info to consider. I imagine that the difference between RIS1.5 and RIS2.0 will be the software. This was the major difference between RIS1.0 and RIS1.5; RIS1.5 was easier to use and (...) (24 years ago, 9-Mar-01, to lugnet.robotics)

That's the one. I used the low pressure version to get the 1/2 watt rating I.E. 5VDC @ 100mA. It works, but it has a few drawbacks....It's a traditional 3 way valve (Com, NO, NC) so it doesn't vent the same way the Lego valves do, you'd need two to (...)
