Fair enough. I can understand leaving out the external ram interface, but 
surely SPI/I2C header wouldn't have cost that much?

Back when I moonlighted as a teaching assistant (beside my day job there) 
for HUT audio dsp course, we wished the boards had had a few 
potentiometers and numerical / lcd display. That should be easy enough to 
add via SPI header. And cheap? - no need for fancy box, just provide pcb 
mounted pots & lcd & something to control & read said things.
Tuning parameters and especially demoing them at end of course was always 
quite painful because of the very limited interface.
