The CF will not work just like RAM instead it works just like a 8-bit harddisk by using memory mapped I/O. Every 512 byte sector must be selected first. But when selected and available it will be as fast as RAM an can be loaded with a single LDIR instruction or in any other way you like. It's also possible to execute code from it directly. But only in a linair way. > (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.) I hope your not to disapointed now. Edwin
