Which model player? Which Hijack kernel?

It really looks like the chip (which?) that is on the upper 16-bits is still not getting the RAS line signal -- the lower 16-bits are zeros as they should be, but the upper 16-bits are just showing the last address strobe on the bus, as if the chip was not driving data lines. That means no chip select == no RAS.

For Mk2, pin14 should connect to RAS3 on the CPU, for Mk2a it should connect to RAS1.

Both RAM chips should have pin14 (assuming Mk2a) connected to the same CPU RAS line.
