Hi guys, I've searched in many places, but with no luck, so if anyone recognise it, please speak out. On the back side, more in the middle, there is a logo imprinted with PCB, but I can't tell which vendor it is. The card is not working, but I've tested the bios chip on w32ax model and it worked. The card has a lot of jumpers, so I actually would need some documentation to get it to work.

Best guess at the moment would be BCM ADVANCED RESEARCH, possibly the GP4000 ( https://theretroweb.com/expansioncards/s/unknown-gp4000 ), given the matching images, that this cards name seems to follow the naming convention of other listed BCM expansion cards and that the cards MTL jumper manual lists JP12 specifically as configuring the card for use on either BCM or non-BCM motherboards.

This is it! Thank you so much! Just an hour ago, I went for another spin, ended up in the Cardex deadend...

It works! It was left jumped on 2mb, while they probably took out extensions, and it shined after I've jumped it to 2WS. Thank you again, it really made my day 😀!

Got one of those cards recently, the BIOS mentions "ColorView" at the very end, so that may be the actual manufacturer.

When jumpered to 1WS (JP8 and JP9 on 2-3 position) it's even faster, and upgrading the memory to 2MB will enable memory interleaving, massively increasing performance on Windows.

Awesome! Thanks for the info! It didn' want to work on 1ws on this mobo, but I'm planning this card for another build anyway. Have to find ram chips though...
