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...?
