variants better sitcom: implement Boot and Reset buttons, implement remapping of low 32kB, hook up PIA, implement I/O space mirrors, hook up RS232 interface for downloading programs, add a software list with two example programs. (nw) sitcom software list isn't hooked up right, the file won't be fed to the -bitb input if you run with the set name; you have to run like mame sitcom -bitb roms/sitcom/san.zip/san.hex
