PIP10 will let you read (and ISTR, write) PDP-10 formatted tapes on a
PDP-8/TC08. Been there, done that. I don't know if there would be a
problem on a TD8E setup. -- Ian

Aha. Interesting. I didn't know that the bit patterns of the control 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.
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...?
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.
