1. The blog is currently the only location where I am posting documentation
(more is needed).

2. Multi-disk programs require their own folder on the SD card. Place the
individual disk image files inside the folder and give them names that end
in sequential numbers (1-9). For example I have Gold Runner 2000 in a
folder named GR2K with the two disk images inside named GR2K1.DSK and
GR2K2.DSK. Use the DRIVE command to mount the folder as drive 0:

  DRIVE 0,"GR2K

This will mount the disk image inside with the lowest numbered name. Each
press of the button on the controller will then rotate through the numbered
image files and blink the LED to indicate which image has been selected.

3. I have tested the board with SD cards as large as 8GB. The firmware can
use either the SD or SDHC interface specs, so any of those type cards
*should* work.
