(...) 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. Presumably the rest is working memory for the firmware (stack, (...) (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

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