Hi all --
Got one of these:
http://www.bitsavers.org/pdf/amcodyne/7110/Arapahoe_7110_Brochure_Nov84.pdf
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

HP used them in one of their disk products, that is probably where the eBay
guy pulled the drive from, since he has a LOT of HP disk parts he's been
selling off.
I also have a couple of the drives, w/o media or any more docs. If we can
identify the HP product, its early enough that HP would have printed a good
service manual.

Thanks everyone for the information -- that definitely looks like the same
drive mechanism. I had no idea HP sold a drive like that.
I think I may wait for the price to come down a bit on those packs, though
:).

I checked my drive, pn 7110S-HP
likely SASI, that DTC board is a SASI to HPIB bridge
Maybe HPMuseum knows where there are used packs. My drive looks like it came off of a
HP1000 system (LU40 and 42)
I just checked all of the scans I made from Crisis Computer's service library and it
figures I didn't scan the
binder with 7907 info. From the binder inventory I did, they had the depot hardware
manual.

I have one or two packs and a drive in the museum but that's all. If I had a surplus
of packs I'd be happy to share...

Right off the bat it looks like a CDC Lark pack. Wonder if the whole
thing is a re-badged Lark.
Once I get these RL02's out of the way I'll drag my Lark out from the
shed and start looking at it. If I recall one drive is in the shed, one
in the attic along with the power supply. Then again I thought I had one
Porsche 911E fuel pump in the shed, but that was sold years ago. Hm.....

There were three different companies that made 8" drives like that, Amcodyne,
Datapoint/Honeywell-Bull, and CDC
I don't think the packs were interchangeable.
