Hi,
We have a friend with a "tape" (DDS, DLT, or LTO ... don't know which yet)
to which was written a system backup. Thousands of files, with an EOF
between each file, and a double EOF + EOT at the end.
The problem:

G'day Steve -
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

manual for these or the Direct Inc. models ? The one i got was a little
bit damaged due to shipping within Europe. Found at least one transistor
and one cap that broke off the video monitor board. Will try to fix that
next week.

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

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.

Evening folks,
Could a stuck bit or floating pin cause this address sequence?
0.14226156250,'3896' (0x0F38) 00111001

I dunno – there’s something about the sheep welcoming the 7070 that struck me
funny.

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