You should look at Kekoa Proudfoots documentation of RCX internals
(http://graphics.stanford.edu/~kekoa/rcx/) and his librcx library
to understand the calling convention for the ROM.
Then get yourself the H8300 tools (gcc et al) somewhere,
this includes assembler and disassembler and the tools to generate
srec, the format that the RCX understands.
Finally, you can use for example nqc to upload your program.
For the documentation of the hardware try
http://www.google.com/search?q=h8%2F3297+hardware+manual
From then on it shouldn't be too difficult to write your simple
assembler program, even with full sensor and motor control,
the ROM routines do all that nicely.
Good luck
