(...) For most Windows users it is extremely easy to set up Cygwin & brickOS (as well as pbForth and leJOS) using the pre-built installers I created. And who needs a graphical programming environment when you've got BricxCC? :-) John Hansen (URL) (20 years ago, 22-Jun-04, to lugnet.robotics.rcx)

I'd also love to see real C/C++ programming support out of the box -- setting up Cygwin and brickOS is just too hard for most people. If (...) (20 years ago, 20-Jun-04, to lugnet.robotics.rcx)

I'm thinking something like a hybrid between the GameboyRCX and what we have now.... What if you could use an IR equipped palmPilot (or Clie), or even a PocketPC to talk to a simple micro. Wait, you'd need an IRDA protocol stack on the micro, unless (...) (20 years ago, 18-Jun-04, to lugnet.robotics.rcx)

I must say, having built numerous active sensors for RCX, I don't think I'd class the interface as hard to live with. Its cheap - (...) (20 years ago, 18-Jun-04, to lugnet.robotics.rcx)

(...) I think using your logic you should subtract the cost of the Gameboy, because, hey, it's a gameboy. I wouldn't mind having one. Then the XRC is $269. Andy (20 years ago, 17-Jun-04, to lugnet.robotics.rcx)

(...) Oh, yes it does. Quite a bit more, actually. The original GBA still runs about $70, I believe, or the GBA SP will hit you for $100. $269 gets you both the XRC and the basic no-frills Xport that connects it to the GBA ($338 will get you the (...)
