# 569 tracks makes for a 2.5MB disk, useful for CoCoSDC images but it's too big 
# to work as a "floppy" on most emulators I know of. As the repo gets bigger, 
# this number will need to increase. The formula I use is:
#
# N * 2^20
# -------- = sector count, where N is a number in megabytes.
# 256 * 18
