[2] Brown, L. C.,  “Flyable TRADIC: The First Airborne Transistorized Digital Computer”,  IEEE Annals of the History of Computing, Vol. 21, No. 4, 1999.  Louis Brown has provided an excellent and thorough description of the Flyable TRADIC, including hardware, programming and project details – this includes material and comments supplied by Homer Coonce.



[3] Irvine, M. M., “Early Digital Computers at Bell Telephone Laboratories”, IEEE Annals of the History of Computing, July-Sept, 2001. Maury Irvine’s 20 page article is unmatched for documenting the history of Bell Labs computers, including a comprehensive discussion of the TRADIC project computers.
