Hi,

The idea that we have is to emulate the mircocontroller of the RCX, that is
we want to emulate the RCX at the lowest so that we can then introduce
whatever firmware or program later.

We have the assmebly language code for the ROM and the firmware of LeJos and
LEGO (Standard).

We have information on the instructions of the microcontroller, but we are
missing information on how and where programs are loaded into the
microcontroler and how they interact with the firmware.

For the hardware you can look here:
http://www.google.com/search?hl=en&q=h8+hardware+manual
http://semiconductor.hitachi.com/products/pdf/h33th014d2.pdf

If you can simulate it and an IR connection that would be enough
to load whatever firmware and program you like, with the usual tools.

Otherwise you can look into the loader code,
for leJOS it is in rcx_impl/main.c and not very complicated
(a few pointers and memory areas initialized).

I think it is a very nice project with many uses.

Good luck

Jürgen

(...) Yes. But that would not be enough. In fact, I was thinking about such an emulator to get rid of some crashes in legOS. But one has to mimic the whole seonsor input and motor output possibilities. Imagine a robot with two motors and a rotation (...) (22 years ago, 24-Feb-02, to lugnet.robotics)
