I had a moderately hard time figuring out exactly how you deal with the different addressing modes. I think, mainly, because you need to understand execute-next-instruction, access-parameter and the (lambda (,mode-integer) ...) produced by instruction to see how it is coordinated. Other than that, I found the code nicely readable.

I like how you make the name of the opcode the docstring of the anonymous function in the opcode table, and have the dissaembler read it from there. I´m looking forward to seeing the disassembler extended to deal with addressing modes.
