What's the capacity of the "MiniDisk"?  Earlier postings
on this camera stated 3.5" floppy.

Assuming the 3.5" floppy capacity is in the ballpark, then
the camera has to store 2000 images in 1.4MB.  Hmmm...

Assuming each image has a resolution of 100 x 150 (15,000
pixels) x 2 octets/pixel (15 bit color), then each image
needs 30KB of storage.  2000 images would take 600MB of
disk storage.

Or it requires a compression ratio of 41:1.  Seems unlikely.
