Yeah, I know I can use DATman on IRIX (I have a pair of O2's and a
purple Indigo2 w/ SolidIMPACT), but going forward I'd like to use my
laptop.
do people really still use DAT audio tape ?
For what it's worth, I dug up out of my collection of 'stuff' a Xircom
PortGear USB-SCSI dongle, bought the appropriate adapter from 25 to 50
pin, and connected it to an SGI-OEM Archive Peregrine/Python drive.
Here's what CentOS 7 sees:

Hmmm, this might just work. The firmware rev is good (01931-XXX 5.63)
and it IS an SGI-branded drive..... now to see if the known Linux
software from ten years ago will even compile, much less run, on C7.
I have a couple of the SGI-branded external Sony SDT9000's on the way,
which are considered more reliable for audio extraction, but the
Peregrine was cheap ($25 including shipping on eBay) and makes a good test.
But I was very pleasantly surprised to see CentOS 7 pick up the
Xircom/Entrega PGSCSI and run with it; nice. So anyone else looking for
laptop SCSI solutions, if you can find a Xircom PortGear USB-SCSI
adapter it does look like it is supported by C7.
