A major achievement was the use of magnetic tape for high-speed storage. During development Mauchly continued to solicit new customers and started a software department. They developed applications, starting with the world's first compiler for the language

Northrop allowed BINAC to sit, disassembled, in their parking lot for a long time before any effort toward assembly was made.

Straus became chairman of the EMCC board, and American Totalisator received 40 percent of the stock. When Straus was killed in an airplane crash in October 1949, American Totalisator's directors withdrew their support.
