It is more complex than the others I have done.Hi Tony, The HP-97 is like a small computer with a cpu, rom and ram, right? Which chip exactly is equivalent to the cpu? Is there a list or description of the instruction set? I have programmed in 6502 assembler long ago, is it anything like that? Is there a rom listing of the HP-97 anywhere (preferably commented)? Thanks, Kees. |
