LEGO Technic Interface A A few days ago, a friend offered me one set 9750 LEGO Technic Interface A with the Interface Card and Cable (IBM compatible) but without software.

Can someone share the installation software (LEGO Lines, LEGO TC Logo or Logowriter Robotics) or where can I download the original software for IBM PC-DOS??
The software for Technic Interface A is said to be the same for the lego DACTA interface (aka 'interface B').

Try this download link for lego DACTA control Lab
