I was interested in writing some assembly code for the lego mindstorm, I don't plan on writing an incredibly complex program though. I am learning asm for the z80 chip so I have a little experience. I only want a single threaded application with one active sensor and two motors running at full power. I am not interested in using LASM as was mentioned in a previous thread. I thought a good place to start would be the early archives of legos development or the early rcx archives although on lugnet it seems the archives start after legOS was already underway. If anyone has tried this or has other suggestions of documentation please tell.
Also I saw a link to documentation for the h8/300 here(http://semiconductor.hitachi.com/products/pdf/h3ltp001d1.pdf) but it dosen't seem to work, if anyone has it please email it to me.

Here's a more direct link for the H8 docs: (URL) down to the literature section and download the two PDFs. For assembly, I would recommend starting off with an installation of BrickOS and perusing the various source code files for the kernel. You'll (...)
