The device is compatible with a wide range of games and is an ideal solution for laptops without a dedicated sound card/chipset or later desktop computers without ISA slots for adapting an AdLib or Sound Blaster card.

Over the years, the hardware has been extensively documented through BBS (bulletin board systems) and across. People have begun to create their own DIY variations because the parallel port connects with the DAC in a relatively simple manner and can be made using inexpensive components.
