Info / packs for Amcodyne 7110 "Arapahoe" drive?

[Josh Dersch]

Hi all --

Got one of these:

sans power supply and packs.  I'm guessing that these packs were specific
to this drive and not any sort of standard, and that tracking one down is
going to require quite a bit of luck.  Figured I'd start here :).  Also
looking for technical info (pinouts for the power connector would be a good
start...)

Thanks as always,
Josh
