Has anyone ever tried to upgrade the memory in the RCX? ( External RAM that is ). What about upgrade the CPU to 60kbyte PROM version?

Something with flash? Would lejos welcome this? Or would it be too much effort to port to another CPU? Any kind of an open source hardware project like this available? Thanks, Rand

The controller plus the all memory is on a module from Phytec "Dipmodule (...) (22 years ago, 17-May-03, to lugnet.robotics.rcx.java, lugnet.robotics.rcx, lugnet.robotics.rcx.legos)
