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.

> Get my cd7 schematic and preliminary board layout (you'll need to autoroute it).

> I don't know if it's clear from the board layout but the db25 connector is installed from one side of the board and the CD-ROM header connector (and everything else on the board) is installed from the other side.
