I have been informed by Brother International Corp. That I am no longer allowed to provide free copies of the GeoBook Disks. Until further notice, if you need a replacement disk you must call 1-800-284-1937 or 877-552-6255 to order them. Be sure to specify exactly which machine you have and which disk you need. The disks are $5.00 each plus $5.00 standard shipping (Shipping is the same weather you order 1,2 or 3 disks).
