The 2920 has been discussed here before, about a year ago. I went through my back emails, but couldn't find the thread.
The 2920 came in some flavor of Pertec, and SCSI via rear-mounted adapter. Yours appears to have the adapter interface. We ran several of the pertec version of these drives in our shop with Aviv unibus controllers. Our drives had basic diagnostic info inside the door, which was quite nice. Unfortunately, my memory is too sketchy at the moment to be helpful. I believe JP Hindin has the service docs (and one of the drives) from my shop, though they may be inaccessible at the moment. --Shaun On Tue, Jun 28, 2016 at 2:10 PM, Al Kossow <a...@bitsavers.org> wrote: > > > On 6/28/16 11:36 AM, Torfinn Ingolfsen wrote: > > > FWIW, there is one on eBay: > > > http://www.ebay.co.uk/itm/Manual-For-Storage-Technology-Corp-2920-Tape-Subsystem-Maintenance-Manual-/301524483917 > > I bought it, and will take care of getting it scanned and on bitsavers. > I've got some other STC manuals in the queue too. > > >
