Some people get Bitronics confused with bionics, but the Bitronics Data Switch Kit has nothing to do with the six million dollar man. It’s the simplest way to share two parallel devices.
The Bitronics Data Switch Kit is the easiest, most economical way to connect two parallel-port devices. Connect a scanner or Zip drive to your PC, or share one parallel device (like a printer) between two computers.
