Well i had an apollo 1260/75mhz which worked fine on my 1d4 which had ioblix clockport.But i sold that because eyetech said the 75mhz version cant have another simm socket fitted due to the size of the chips on the back.So i bought a blizzard 1260 and also a powerflyer the powerflyer works fine alone but if the 1260 is in the screen goes red.
