Unknow ISA Video Card (Yamaha V6363)

[marminsky]

Hi everyone,
inside a 5150 I found a multifunction card (video + parallel + floppy controller). I've never seen it before and I don't know who the producer is. Can you give me some indication on how to configure it? What are jumpers for? Is there anyone who has a manual? Thank you very much.
If it can help, mount the Yamaha V6363 chip.
This is the link to the video where you can see the card: https://youtu.be/YzSpLqPagLw

Can you tell me what card is this? Thank you.

Gabriele

I add some photos of the card.

Hmm there are probably many people with better knowledge than I. But if You want to known my opinion...

There is a chip with "2" on it. Maybe it's just something similar to EPROM? If You can copy it, maybe it will show something in editor?

Over this chip is some text - like "Made in Taiwan R. O. C." Near C-31 is GPF-103. So maybe it is some product called "GPF-103", that was made in Taiwan? You should also do a photo of reverse size.

Interesting card. I have never seen a CGA/HGC card combined with a floppy controller. Looking at other V6363 cards with parallel ports, the jumpers and switches should choose between MDA/Hercules mode or CGA mode or to use the composite connector* and which LPT port is used. The solo jumper near the floppy connector could possibly be to disable the floppy controller. Exactly which switch and jumper does what is something I can't be sure of. Someone with more experience than me might be able to track the traces from each switch to see what it is likely to do.

* I am guessing that is what the vertical connector next to the bracket holder is.
