Any functional drive having a working tray mechanism can be used to connect to the MPEG-1 decoder card. Latest Decoder cards ( hardware version 3.0) of today are widely available and manufactured by some chinese companies that use SAMSUNG's or SONY Video Logic and motor servo controllers. As a result the existing motors i.e. SPIN servo, Eject servo and laser head servo can be used without the need of changing them. Firstly, remove the old PCB attached to the motors (For all systems, CD Drives etc.) and then Just connect the ready-to-use MPEG card to these motor and controls. What's great is that these MPEG cards come handy with remote controls and toggle button boards for media controls. These MPEG cards can play MP3, VCD, DVCD, SVCD, ACD, and even cards can support playstation standards. Morever nowadays, MPEG- 2 cards (that find use in DVD's) are approaching.
Connecting the MPEG card:- I suppose the older board must have been removed by now. now find a respectful place for the MPEG card and place it carefully, protect its electronics such that it does not get touched with any metal case or risk of shorting. Now connect the respective wires to the motors. Now u have to supply power to the card. These cards take 5V and 8V instead of 5V and 12V for computer system. So if u r using a computer interface to derive power, use some resistance to reduce it. Now u'll find that the card has ready-to-use stereo output, so it's not a big problem connecting to a TV system. Next the video has 4 cables; don't worry it's S-Video, so u'll need a small circuit or a cable that converts S-video to composite video(RCA) as older TV's don't have support for S-video. I bet the image is very detailed, crisp and clear. Not to mention the surround sound feature of this mpeg card, i recommend it to all who want to upgrade their drives to vcd/mp3/acd system at minimal fuss and cost. Item of surprise: This MPEG-1 card can be found in indian market for anywhere from 700 to 900 bucks.
