Gravis Blackhawk adapter

[GiantCake]

I found a old joystick that my dad used to use. I want to use it again for games like War Thunder. The plugs are old enough that I dont even know what theyre called. It has two ends. Circle plug with 4 pins, two on each side that slants towards the center, and a tiny black stud. The other end is the opposite. It seems to be able to fit the first plug in. Unfortunately I cant add the picture. I hope I described it well.

That sounds like the ps/2 passthru for the keyboard. there should abe a 15 pin gameport connector too.
