MP3 Prototype #2 for Laptop HDD

This version uses EPP to transfer data to a 2,5" HDD. The powersupply is a 5 volt switch mode and the display is an Optrex DMF5001N with EL backlight (not used in this version) and a Toshiba T6963C IC.

Viewed from the top, all you see is the power supply, the buttons and the MP3 decoder board.
