Quoted from Nihonmasa:That's what I feared Would you know the ref? can't manage to find it
You need a 4.7K bussed 9 pin resistor SIP. The original SRCs are no longer available. They integrated a pull-up resistor and a noise filtering capacitor into the same package. In practice, you won't notice a difference by not having the capacitor in the circuit.
But you really should properly abate the alkaline corrosion which means removing parts, sanding to bare copper, replace parts, conformal coating bare copper. It's tedious but doable on System 11 MPUs. The sooner you abate the damage, the better the chances of success.
