Wow is right. The rumor is almost definitely wrong. Compression technology
of a random bitstream is lucky to get 50% compaction. The compress program
used for passing news around averages between 35% and 45%.
This may be a "best case" compression, something unrealistic like a Macpaint
image of all white or black pixels (neither of them very useful). I doubt
seriously they can get even close to that on a normal bitmap. Think about
it logically -- a 31:1 ratio implies that each bit in the compressed file
needs to hold information to recreate 31 other bits. Not very realistic.

The Dvorak rumor mill has come up with this one. Lots of people who have
signed non-disclosures giggle at Dvorak, but can't say anything more. The
rumor was NOT for a Mac, but for the first in a new family of computers that
would not neccesarily be Mac compatible, but would be the first Unix based
machine. I wouldn't hold my breath for it.

O how they cling and wrangle, some who claim
Of Brahamana and recluse the honoured name!
For, quarrelling, each to his view they claim,
Such folk see only one side of a thing.
