(...) I dont know what the max distance for two RCXs is. But i have had the infared transmitter as far as 40 feet from the RCX, with no obstructions in the way and they still communicate. I would bet they have a pretty good range. Jeff (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

(...) There is no user memory from 0x4000 to 0x8000 - It's all ROM space but it might not be used. I look at things in terms of replacement firmware, and the RCX is very flexible in this regard. The RAM for replacement firmware starts at 0x8000. (...) (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

What is the maximum distance for infrared communication between two RCXs (say with new batteries)? Do the RCXs have to 'face' each other? Thanks, Michael (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

Well, I checked with Kekoa's memory map, and indeed, thinks are not as simple. And Dave was right (Why did I doubt is sacred words?) Memory is divided into three main area of 16k. The first is ROM, containing the base programs. The two other (...) (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

Thank for the answer, Dave, this is the kind of info I'm looking for. BUT! I don't think it is correct: 0x8000 is 32k: the firmware would start at the end of memory!?! 0xbfff is 48k: unless the 16k of the rom are counted of course... Then this mean (...)
