the card is nice because IIRC it has four megs soldered down on those first chips top left, 8 on planar and those four would bring you to 12 megs without having to worry about simm clearance ! good find.
I had completely forgotten about the Kingston MCA cards until I was researching 386-486 upgrades and saw the Kingston socket-style ones! It's been 20 years since I've played with PS/2 stuff. Coming back slowly
