Is there anything on the back of the card like a FCC is number or any stickers?

A google for "cei isa video tuner" (without the quotes) led me to https://www.tldp.org/HOWTO/BTTV/mfgr.html
which contains:

CEI (Chartered Electronics Industries Pte Ltd [CEI] [FCC ID HBY]) --- TV Tuner - HBY-33A-RAFFLES Brooktree Bt848KPF + Phili […]

A further bit of googling yielded this https://www.datasheetarchive.com/pdf/download … =O&term=MVM121A
which contains a circuit diagram of a video capture card that vaguely looks like yours, except that your board has two RAM devices, and the design has two banks of three.

HTH

It's FCC number is HBY33A-V9.

A bit of rummaging through Google using that FCC number (I didn't know it was an identifier or anything otherwise I would have done this originally!) also identifies the card as a Prime Time TV like mdog69's quote above.

Stason's got me covered:

I might just stick it in my Windows 98 PC and see what happens.

However Googling Prime Time TV ISA card doesn't throw up any drivers or anything.

what will you be using the card for?

The plan was to mess around with capturing S-Video footage of... things, and I was intruiged by the VGA looking port - is it for VGA input? Is it a pass through of some kind? Now I've found the card on Stason it's definitely an output and the port next to it is described as "Loop back".

I thought it would keep me occupied for a little while (and it is succeeding so far)

Edit - here are the ports:

Usually on tuner cards, they carry the workload of video decoding because the PC was too slow. The VGA feature header was connected to the graphics card to feed the video memory data directly to the capture card so the real-time video could be overlayed onto the monitor.. the VGA of the capture card would then output both your computer desktop picture with the overlayed video stream.

Edit: per the TH99 documentation, it shows the VGA port as video output, so that makes sense for video overlay from the other inputs.
