I am quite partial, but you might find interesting to build a 128kb ram and IO extension, viewtopic.php?p=2047#p2047,
then try to browse a sdcard attached to the spi bus, viewtopic.php?t=332 .

Very nice, clean work. The white paint covers the conductor tracks, which immediately gives a different picture. Also very nice solution for the DAC (R9).
If you want to follow lb3361 recommendation, you can get a PCB from me.
