I've got a Floppy Emu from BMOW (and recently ordered a CFFA3000). I'm thinking that I would: write some simple "hello world" code, assemble it, make a disk image on my PC, copy it to my Floppy Emu SD card and boot the machine, and hopefully it would run my "hello world" code. I'm hoping that this will help me to learn more about the boot process, where initialization code gets loaded into memory, layout of the code on disk, and about disk interfacing.
If you want to see some examples of code that fits in the boot block for 
Disk II images:
