The original F8 processor (not the later single chip 3870) is a rather 
obscure beast which has ROM modules that contain its own independent PC 
and stack. Its focus was largely embedded applications and also video 
consoles - the board you have found might be an intelligent I/O 
subsystem that was connected to a real CP/M system if the presence of 
CP/M floppies is not just pure coincidence.
The F8 itself is not at all compatible to the 8080 or Z80 so it won't 
run CP/M, not even emulate it.
