Based on the bios of the authors, I'm actually more inclined to believe the

Hi
I've had the same problem some years back, with a DDS-3, IIRC
I did some research, and the most reasonable outcome was that it was not
possible by normal means, because some algorithm reading synchronisation
data couldnt find out what was happening, so, the backup was ruined.

The 7070 was announced in Sept. 1958, but did not ship until April 1960.

AOS/VS OS tape drive base names are MTA, MTB, MTC, etc. and do not
directly correspond to the assembler mnemonic name(s) - don't be
confused by this difference.
The AOS/VS 'MTA'-type tape drive is described on page IV-5. These
correspond to the original DG model 4030/6020 unit

I have a 1980 "Peripherals" manual (014-000632-01) from the
"Programmer's Reference Series" which covers the MTA type, but it seems
that the MTB behaves a bit differently and I am missing some informa
