Cassette sense on the C16 is implemented using the 74LS125 at U11, a tri-state buffer. However, this is also used to drive the joystick selects, so if your joysticks are working OK, it's unlikely that.
The other possibility is that the cassette sense line is being pulled to ground. Check for shorts, the ceramic capacitor at c25, and the 3.3k pull-up resistor at r12.
