Yes, its pin 32 I think on memory exp slot - you will know youve got the right pin because its joined to pin 32 of Gary (check continuity using multimeter). Ive added a fast(slow) / chip 1Mb switch on mine. You also need to toggle the JP3 jumper as well (I think its JP3) - located between CPU and ROM on rev 5 PCB.
Looks like 8375 is pin compatible, I guess no one tried it before.
