this is always good news.  now to figure out how to get the third cardcage into
an sgi rackmount onyx without needing 3-phase.

one of them converts chucked mentioned is always an option, but i'm always
looking for the cheaper rewire-that-machine option if it's available.  :)

i will have to make an effort to look.  i have a 7000 here (well, it used to
be a 10000, but it has had its expansion cabinets removed, so it's basically a
7000 now) that i could look at and let you all know.  i'll try to do that
tomorrow when i get home from work (so that there is sunlight out so i can see
in my lightless garage.)

gh, that reminds me.  where to put the 9000?  wish i could build a small shed
on the land here.  plenty of space.  live in a damn state park, they don't let
us build.  it sucks.
