IBM 6157 Model 002 Tape Streamer

[Chris Teuben]

We have an IBM-6157 Model 002 Tape Streamer, without the hardware specs.
Who knows these specifications? (# of tracks, density etc.).
What is the backup command to use the full capacity of the streamer?
I tried to get an answer from IBM Technical Support, a few months ago...

Thanks in advance!
