I have some good news too. After a long time I finally have made a CF interface for SAM that comes in a light version of the Atom
Light meaning it is has 8-bit wide databus. CF-card are accessed in 8-bit mode. So no capacity is lost and speed is even faster. It's designed in such a way that it fits in the right floppy disk drive bay without the need to open up SAM.
It is also compatible with most existing Atom software (some minor changes are needed in some cases though) for example I didn't need to make any changes for the Atom versions of Prince of Persia
