I built a disassembler years ago to pick apart
captured malware. By
now it handles about a dozen ISAs. While 8080 and 8085 are not on the
list, Z-80 is; adding 8080 would be a relatively simple thing. I've
added that to my to-do list; if someone can point me to 8080/8085
machine language documentation that would save me some searching (which
is something I'm not much good at in these days when frickin'
*everything* is shoehorned into a Web page).
You mean something like this, from another disassembler project:
