Anyone have one of these RTTY terminal units?  I have not been able to get complete documentation on it.  I was able to get documentation of the 402 unit. Its close but differs in some areas from the 402DL.  Anyone using or have used one?  I would like a manual or to where to find one?

Mine does not have any of the option boards.  Its pretty sophisticated for a unit that's 50 years old.  I have not turned it on yet as I'm trying to get familiar with it first.
