This looks great! I'm especially interested in this, since I only have a single 1 meg card. I have a few questions, though: Is this just as fast as the SAM's internal memory? (I don't know whether or not the 1 meg card is slower.) Also, how expensive is paging? (I will need to do paging every few instructions, since I'm mainly interested in using CF as extra memory, rather than as disk space.) -- Stuart Brady
