I've added RCX 2.0 support and filled in a lot of the missing features. There still are a few odds and ends that need to be implemented, but most programs should be able to be simulated on it. This is still only the core simulator and not a full GUI (...) (24 years ago, 19-Nov-00, to lugnet.robotics.rcx)

Yes, it's possible. You get less voltage with NiCads, so the motors don't turn as fast as they do with brand-new alkalines. Plus they don't last as long. However, they're so much cheaper to run! I used to use NiCads during development and general (...) (24 years ago, 15-Nov-00, to lugnet.robotics.rcx)

Yes. Install the "extras" from the "project" menu. You will then get a yellow stop sign, which floats the motors instead of brakeing them. Wire in the ports to be floated. -Peter Coach, FLL Team #1096: The Unibots "J G Gregory" <jgg@ultranet.com> (...) (24 years ago, 17-Nov-00, to lugnet.robotics.rcx.robolab)

I could send you a copy of the Legos Kernel (legOS.srec and legOS.lds) files I am using and you can see if your code compiles and works better under it (actually I am using a patched version of 0.2.4, a early beta from Luis for what will most likely (...)

So what causes it to 'forget' the firmware. Doesn't it store it in Flash memory? Or does it require batteries to be installed all the time? Matt (24 years ago, 16-Nov-00, to lugnet.robotics.rcx)

I also have a LegOS 0.2.4 program that uses two rotation sensors on input ports 1 and 3 as well as another active sensor (the Technostuff Dual IRPD sensor) on port 2. All work flawlessly, no counter drift noted on the rotation sensor. Perhaps it is (...) (24 years ago, 16-Nov-00, to lugnet.robotics.rcx.legos)
