Love to see some pictures, and a couple of a board.  


I once needed 2N404A's for a project and over the years collected a few  
boards.

This  gadget was described in September 1965 QST on page 105.  The 
ARRL used  one for their CW bulletin transmissions. 
I think  there was a manual on Ebay not too long ago.

Thanks to Larry K7KSW I have recently  acquired a Frederick 660A 
Baudot-to-Morse Code Converter. Now I desperately  need a manual or to contact someone 
who also has a 660A. 

Mine is  missing 2 PC boards, which I am can replicate if I can find a 
schematic or  boards to copy. If you ever come across any 4.5"x14" boards full 
of 2N404  transistors and labeled N0133 or N0145, please grab 'em for  me!
 
Photos of the unit and other  PC boards is at
http://www.navy-radio.com/morse.htm#660a
 
I have all the code converter boards which provide a  diode logic 
conversion from baudot to morse. It also looks like I have the  boards for input and 
output relay control - I'm guessing the two missing  boards provide some 
shift register logic, handle LTRS-FIGS shift, convert  CR/LF to BT, etc.

And thanks to Jim N4BE I have  added several more Frederick manuals at
http://www.navy-radio.com/manuals/tty/frederick.htm
Cheers,
