I believe you can do this on the TC11 with the READ-ALL operation, but my memory is vague
and the manuals I have handy aren't detailed enough.

Aha. Interesting. I didn't know that the bit patterns of the control channel was
different.
Curious question then - could most DECtape controllers even read LINCtpae?
I know the TD8E can. The most stupid controller on the planet, but it enables you to deal
with just about any DECtape format you could possibly ever invent.
But other DECtape controllers might not be able to deal with tapes that use other codes
to indicate what is being read...? LINCtape is essentially identical to DECtape. I
think the directory
format is different, but I think the block format is the same. I think
the tapes are wound in reverse order and the order of increasing block
numbers is reversed.
Actually the block format is different. "Obverse Compliment" encoding
was created for DECtape. LINCtape blocks aren't bidirectional.
