I recently rescued this very unpopular 386 computer in very bad shape.
Now I want to attach it a soundcard, but ISA riser is missing, so I can't plug it.

The only one computer that looks the same is here: https://oldcomputer.info/pc/Philips200/index.htm
Even being a 286 model, the riser should be the same in my Philips PCD 304/00 . I would talk with the owner of the web to see if can get me a pinout, but no email or contact way there. Someone knows how to talk him?

So I just tired up and fitted the ISA card into the port, but it gave some beeps and refused to boot. Idk if it's 2 8bit ISA slots, or a 16bit slot with pinout changed, or... Suprise(?)

I don't find ANY information about this board and it's riser. PWA-MS386SX BD . It's not a Phillips, but a strange mitac board which is no info anywhere. I tried to follow the lines to the chip controller of ISA, but it's so difficult and I don't find also pinout of the chip.

I'll try to give pics of the ISA (?) port.
