> I took my CD7 apart. Took some pictures of it that I haven't got around to uploading yet. Tried to email the couple of people that expressed interest in it before but didn't hear anything back from them. I had said that if nobody would commit to building it that I wouldn't go to the trouble of drawing out the schematic.

At first I couldn't believe how anyone could make such a simple interface board for a CD-ROM and have it work but after taking the unit apart it all falls into place. It doesn't use an IDE CD-ROM drive! It uses a Panasonic (Matsushita) proprietary interface (MKE). The drive is a Panasonic (Matsushita) CR-563-B 2x unit. Some of you may even have one of these laying around because they shipped a lot of them with Creative Labs SB16 CD-ROM kits. There is also a CR-562 that is basically the same drive without the digital audio out on it.

> The interface board I have also looks like it has an option to use a serial interface and possibly use a Sony proprietary interface instead of the Panasonic. The Sony parts aren't stuffed and I'm not going to bother trying to trace those out. My PCB will be Panasonic only.

> I hope to have a schematic done by Monday. It will probably take me awhile to get the PCB design done because I'm just a beginner at that.
> I plan on getting a external IDE case with a parallel port interface and replace the parallel port interface board with the CD7 interface.
