Pioneer Electronics (USA) and NEC Home Electronics released this module that allows users to play 8-inch and 12-inch LaserActive LD-ROM² discs, as well as CD-ROM² and Super CD-ROM² discs, HuCards and CD+G discs. The Japanese version of the PAC can also run Arcade CD-ROM² discs through the use of an Arcade Card Duo. The retail price was US $600. It came with a LaserActive-branded version of NEC's Turbo Pad (CPD-N1/CPD-N10). An NEC branded version of the LD-ROM² PAC known as the PC Engine PAC (model PCE-LP1) was also released. Due to the unpopularity of the TurboGrafx-16 in North America, very few PAC-N10 units were produced, resulting in their scarcity compared to its Sega counterpart.
