I can't remember if you wanted the option ROM pinout for the model 100 or the model 102 (I'm offline now), but here is the pinout for the model 100 option ROM. 1. VDD 15. AD3 2. A10 16. AD4 3. A7 17. AD5 4. A6 18. AD6 5. A5 19. AD7 6. A4 20. A11 7. A3 21. /DE# 8. A2 22. A13 9. A1 23. /CE# 10. A0 24. A12 11. AD0 25. A9 12. AD1 26. A8 13. AD2 27. /CS# 14. GND 28. A14 # ROM PIN SYSTEM /DE 21 /RD* /CE 23 ALE /CS 27 /Y1 Source: Service Manual. I hope this helps. RICH The pinout for the model 100 and the model 102 is the same anyway.
