I should note that this is almost 10 times faster than the Coherent Chips.
Given that there is no need for interprocessor message passing in the
DES tests, I rate that this chip could be 20 times faster than the
earlier design. That puts it at 100 days per DES attack.
This sounds like a pretty fun machine to get. All of the old vector
performance of the Cray bundled with the fun of the old CM-1/CM-2.
You could get some _great_ results on specific problems.

Along with many others, Peter Wayner discusses craching DES:

I really don't understand what the concern is here. We all
have access to crypto that is much stronger than single DES.
Anybody who is using single DES for something so important,
that it is worthwhile to spend 100 supercomputer days to
crack it, is really such an idiot that they deserve whatever
they get.
