Is that what's called the 'shrink-dip' package in parts of the
industry?  I remember years back having to order some special ZIF
sockets to make use of them with an NEC micro we were using.  And
just last week I was looking through the detris from the old
electronics lab at work and noticed a fragment of circuit board
designed expressly for mounting one of those chips.  It had been
chopped up, though, by some cretin who used a part of the 0.100"
pad layout for some other purpose.  So apparently there are
prototyping boards available to adapt that pin spacing for
breadboarding/hand-wiring purposes.  Back at the time when we
were dealing with it, I just epoxied one of the (expensive, large
minimum order) ZIF burnin sockets onto a standard 0.100" spacing
header to make an adapter.  Awkward but it worked.  Search on
'shrink-dip' which I believe is the term for chips with that
spacing.
