Hi
Just curious, is this basically the cypher drive with HPs GP-IB added or
truly an HP design?

any idea as to what the interface is? is this
scsi or hpib?
I think it could be either. The 7980A was HP-IB, the 7980S was SCSI.
Here's an HP Journal article on the drive:
http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1988-06.pdf
A few years back I picked up an HP-IB 7980A from Ft. Lewis
(govliquidation) in the same cabinet as the one in the current auction. I that drive away since it had problems and
wouldn't load a tape correctly.
Still
have that cabinet though.
I got mine for nop, and it did not auto load correctly too.
But after a good clean and letting the motors run for a while on my bench
psu (cleaning the collector and brushes), it is loading correctly now.
These drives are very robust and you can change the complete configuration
on the front panel.
Mine has a HP-IB interface very handy with all the other HP-stuff I have ;-)
The service manuals are available at the hpmuseum.net site.
