    I think this has been covered a few times already. The cards are very similar but different enough to be incompatable !

    Both contain Atmel processors - the Funcard an AT90S8515 and the Megacard a Mega163. The 163 processor is a logical superset processor of the original 8515 and has an enhanced core (extra instruction - hardware multiply etc) as well as greater memory size (Flash, RAM and EEprom). The 163 also has enhanced peripherals although they are irrelevent in this context (you cant use them because they are on pins which are not brought out in a card environment).

    You must program the cards with the correct hex for that particular card type. The actual source for the hex is actually based on the same core code but the Mega code is optimised to use the hardware multiply. The 8515 code is effectively at its limit in terms of size - their isn't a lot of flash memory room left !
