Sounds like an interesting project. But I'm a bit confused. I've sent
you via private email the assembler you are looking for. What hardware
are you looking to write/disassemble code for? Are you talking about
something that exists in the hardware of the Intel Series II development
system? Off the top of my head the only 8041 is in the keyboard, but I
may be forgetting one.
I have a few working MDS Series II systems in various configurations.
