Seems to be an TV tunner card, I saw similar without additional PCB, what this for?

Yes it is almost certainly an AverMedia TV tuner card - that's what the shielded box is for. I'd guess year of production to be 1999 or thereabouts, based on the warranty sticker on it. The added board looks like some sort of hack - it's taking an audio signal (and maybe more - can't clearly see what the other wires are hooked into); perhaps its enabling audio output from the board itself, or encoding the audio to some other format, etc.

Avermerdia PCI TV tuner card from 1999.
For countries that use PAL D or PAL K systems (the PDK box is ticked).
Uses pretty standard BT878 analog video capture chip.
The extra board is for decoding stereo audio from the IF signal, you can google the chip type if it is just analog stereo decoder for TV or FM radio, or perhaps digital NICAM decoder for TV. At least it is controlled by Atmel microcontroller, AT89C2051, which has 8051 architecture.
Without this extra board they usually just supported mono audio.

While I agree with this, you can fix this in most browsers. You can right click the image and select "View Image" and the browser will resize it.

Yes, I always resize befor posting. This time I decided to upload like this, you can right click "Save picture as". Resizing will change resolution and quality, however I still used worse camera for this. I just want you to see as much as you can.
Thank you for all answers.

Yes, obobskivich you are right, this additional PCB is some sort of modification, I open the screws and realized that MADE IN TAIWAN is drilled through for the screws placement, I'm pretty sure this surgery wasn't done over original production. Apart from that, very well done soldering work, four wires comes from that PCB to the card. This card was pulled from original ABIT SA6R Socket-370 i815E + RAID ATX system, so the story of this PC comes from demanding retro hardware enthusiast I presume. I'm in work right now, when I back to home I will do some more pictures.

Godlike!

Use image hosts such as imgur that provide you with bbcode thumbnails that link to full image.

/\ Just hold CTRL and use the mouse wheel to change the zoom level. Then CTRL+0 (not the one on the numeric pad) to change it back to default.

Let me jump in here:
First of all, there's no reason not to embed/attach photos inline here at VOGONS. So far as I know, Qbix has fixed the auto-thumbnail-generation code and it's good to go.

Secondly, Godlike chose to host his images on Imgur (a good choice)! After you upload there, you'll see that it can generate code for:
Sizes: Original, Small Square, Big Square, Small Thumbnail, Medium Thumbnail, Large Thumbnail, Huge Thumbnail
Code types: Image Link (email & IM), Direct Link (email & IM), Markdown Link (reddit comments), HTML (website / blogs), BBCode (message boards & forums), Linked BBCode (message boards)

For our purposes here at VOGONS, choose one of the sizes (given my display resolution, I prefer Small or Medium Thumbnail) and either BBCode or Linked BBCode, and you're good to go!

As an example, I have edited the original post for you, Godlike, to have Medium Thumbnails with Linked BBCode, so people can click to go to Imgur if they want the larger size. Once you understand Imgur's code, you can even do things like link to the larger file and bypass the Imgur interface, and write the BBCode yourself from memory 😀

Keep in mind that this is all contingent on users' display resolution. On mobile phones, even Medium Thumbnails might be too large.

Back on topic, "302AAABM" might merely be the name of the tuner component but it seems to come up in Google results paired with:
AverMedia M168
AverMedia M168-T
AverMedia M168-K

However, pics I've seen of these don't have the daughterboard, but that may identify the base board.

I'd be curious to see the results of plugging it in and identifying it by PCI ID code.

I have a similar Hauppauge card. (Model 44001) AFAIK, bt8x8 stuff shared a generic PCI code.

As for drivers, you can try to use some of the generic ones floating around. I know there's one based based on the reference driver code, and one written from scratch. (FYI, I didn't seem to get the official Hauppauge drivers running on Windows 7. I usually have had luck with XP drivers on 7, but no dice)

Thank you Stiletto for editing my pictures! I have another pictures upcoming for upload. Please instruct me on PM about BBCodes you've used for thumbnails to IMGUR. I wish to learn and keep neat posts. I have new pictures of PCB and cable connection. Best regards

Godlike!

EDIT: Thanks calvin for links to drivers, I'll try them out

BT878 chipset TV cards was very popular during the times (1998-2000), since they were being supported by third party programs like MoreTV and people were using them for decoding nagravision coded payTV channels (which was popular in some countries during the time, including mine). Although the video decoder was very nice and working efficiently, sound decoding was not so (lags and distortions), so it was also common practice (at least around electronically able people) to put together some hardware sound decoders. Though, I always seen them in separate small external boxes (getting the sound from TV card's output and passing it to the sound card's input after decoding) this additional contraption might be just it.

Cable connections of additional PCB, special thanks to Stiletto

"MADE IN TAIN" says this is exact home made mod, no sharp edges on mounting holes, very good soldering, I'm quite impressed
