Here's the latest update. Hope we will get a clear picture of this #@$@ memory after all. The point is that the RCX processor can address 64k of memory, so let's divide this range into 4 equal area of 16k. (note:16k or 16384, in hex is 0x4000). (...)

The third area is user (and system) data, allocated from the top down. They "meet in the (...) (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

(...) 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)

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 (...)

(...) I believe it has a 16K ROM and 32K SRAM. Within the 32K, 16K is occupied by the 'firmware' downloaded to the RCX. About 6K is reserved for bytecode program space and the datalog.

I'm trying to figure out how much memory the RCX has.
