Unboxing parcel with world's first hdd-based mp3 player!
The Personal Jukebox (also known as PJB-100 or Music Compressor or HanGo PJB100) was the first consumer hard drive-based digital audio player. Introduced in 1999, it preceded the Apple iPod, SanDisk Sansa, and other similar players. It was designed and developed by Compaq Research (SRC and PAAD groups) starting in May 1998. Compaq did not release the player themselves, but licensed the design to HanGo Electronics Co., Ltd. of South Korea.
