It appears to hold the cirquits needed for CD playback. Also has the audio jacks for left and right. Must be from a very early CD-Audio drive. Not sure if it can capture data digitally - at least it has an USART chip.

Probably a CD-ROM interface given the Philips chips and CM154 and LASER MAGNETIC STORAGE INTERNATIONAL markings.

There is a mention of a Philips CM 154 interface in this article about CD-ROMs:

There's a photo of what should be the CD drive that goes with this thing:

I actually also have three internal drives for this card and also the cables.
All drive seem to need caddies, that I dont have (grmbl).
One is missing brand and type information, the other two are from Laser Magnetic Storage International Company (type CM201) and Philips (type CDD200/01).

So the two things I need now are driver software and caddies...hmmm

Probably a tantalum cap shorted. Sometimes they'll put on a good light show without exploding completely.

If that's what happened, it's not a big deal. Just have to track down the offending cap and replace it with either a new tantalum or a low-ish ESR electrolytic of similar value.
