Hello All,
Impatient with no update with an option to set the base address, I downloaded "Hex Fiend" for Mac OSX, did a search for D80001, and replaced the single instance at offset 1632 (overwrote) with EE0001 (the address of my clockport on my Zorrology card) - Sensor now works in my Amiga 2000 with my Zorrology card, yay! (Note - no RTC with this solution, just Sensors), the Zorrology card expliclty states it will not work for RTC, and thats ok by me)!
I don't see why this would not work for anyone as long as you know the address of your clockport. Tempted to buy another for my A1200 again now....
