I'm going from scratch with the J-11, it won't run UNIX, my only real "goal" is to have a self-contained unit, something with a bit-mapped display and direct keyboard input, not just a serial port. I will probably use sram, and for permanent storage, long term, I'd like to do more with EEPROMs, but for starters, probably an SD card.
