[GreenKeys] TT-98 Line Feed on Carriage Return

[Steve Garrison]

AH!  You are absolutely correct!  That being said, does that indicate that I never worked on a C or D model?  Or at least if I did, they all had this feature disabled.  Like I said, 50 years!

Steve & Nick,

Seems like I remember that adjusting the 'extension' on the top of the carriage all the way to the left accomplished the same thing.  And moving it to the right allowed some variation in the character count in the line where it would activate.
 
But it's been years (like 50!) since I've messed with that adjustment.

I think you are thinking about the automatic LF+CR at the end of the line. It was adjustable for line length. All the TT-98 models had that and I think there was a version of the TT-4 that had it too.
The TT-98C & D also had automatic LF for every CR.

FWIW

There was a M28 mod that had LF on CR and then ignore the next two non-printing characters, so CR-CR-LF would only give one LF. 

I was trying to think of a way they (KLI) could have made the machine smarter to alleviate the problem.  KLI never had anything like the M28's stunt box. This M28 mod solves most of the problems, but relies on the "standard" CR-CR-LF sequence (which would have been pretty standard in the military). But what about at the end of a message, wasn't there supposed to be a set number of LFs before the "NNNN"? That would vary depending on whether the receiving machine had this mod. I guess it was not as big a problem as typing over a line.

have fun,

Duncan
