it's not so very impressive. the 8080 is quite an easy processor to emulate (but not at the transistor or i/o level) - you can do it with a switch - there are only 256 possible instructions (not all used). i wrote one on the Dec10 back in the early 1980s (with assembler, disassembler and debugger) in Fortran77 and ported it to VAX and IBM 4381. we used it to teach assembler programming at the polytechnic i worked for. you could easily (well, relatively easily) have written basic on my implementation.
