A datassette module that makes it possible to play "data" from a PC soundcard to the CBM / PET and play "data" from the CBM / PET to the PC. The IEEE-488 module has an SD card and a micro processor. You can use the commands LOAD, SAVE and LOAD "$" to load or store data on the SD card. The device number can be changed with a help of a jumper. The USB cable is used to provide 5VDC from the datassette module to the IEEE-488 module.
