Hi-End CD player using a CDROM

the CDROM Controller kit

by Mr. Sakda Eamkulworapong

It is possible to build a Hi-End CD player using a normal PC CDROM.

To use a CDROM without a PC it is necessary a uProcessor to emulate the ATAPI command protocols through IDE bus.

If the spdif output of the CDROM is connected to a good DAC the sound quality will be at the same level of many hi-fi and hi-end products.

Actually we have 3 different board models:  the first two are standalone CDROM controller and the other is able to play also mp3 files.

All the boards have the following functions:

All the boards use a uProcessor, Atmel AT89C52 with a clock at 11.0592Mhz.
