	You are quite right.  I got the calculation wrong.

	1024x768x15 = 11796480 

	Last night around 4a this looked suspiciously like
2^20 (ie 1M).  Of course, this is the number of bits not
bytes and is off by a factor of 10.  So, several hours of
sleep and a calculator with a Y^X key later I see that it is
actually:

	11796480 bits x 1 byte/(8 bits) x 1M/2^20 = 1.40625Mbytes

This of course, rules out the possibilty of this ad being
correct, which John has confirmed by talking with USAFLEX.

	Thanks for the info John!
