No doubt I'm not the only one rushing to buy a 1GB Microdrive for NetBSD 
now that they're out.  http://www.1unlimited.com claims they have some 
in stock for a very good price, but it is a lie.  They are not in stock.
so, save yourself the bother.  You may as well queue up with the hoardes 
on a more reliable vendor.

If you are planning on a new NetBSD/hpcmips machine, you might make 
sure you can actually get delivery of the Microdrive before you count 
on a working system.  I've been waiting a very long time, for various 
reasons.  Best wishes,
