@stanlong: Hiya. I have tried during my many years as an Amigan - and succeeded. From the linked image would I be correct in saying that there are just 4 jumpers for memory configuration at the bottom centre of the card? Seriously, it's just memory allocation, nothing is going to blow as long as you remember to power off the Amiga between jumper changes. Ahh gone are the days of the pioneering Amigan - He Who Dares....
Good look mate, and remember - have fun, it's what it's all about.
