Kann man ohne "Stecker" auch etwas damit machen ?
SIO connection is optional, it allows full ATR (floppy) support (there is support for ATR even without the cable but it's limited since it softkicks patched OS and that method doesn't work with all software), ATX support (copy protected floppies, not really needed, everything is cracked these days) and CAS support (nobody uses cassettes anyway)
Given that almost all games are available in CAR (cartridge) or XEX (executable) format, you don't need the cable for casual usage.
(Sorry for writing in english, hopefully it's not against the rules (i can't find them) but i don't dare to form a german sentence with more than one word (two at maximum))
