We talked HAL Communications of Urbana into contributing to W9YB their bare board microcomputer with matching video teletype board.
I recoded my Morse Code Teacher in 8080 instructions and made it available to students studying for there amateur radio license.
I also got to know some folks at HAL. We met later at the Dayton Hamvention where I was showing off my Radio Network Simulator. They introduced me to ARRL technical folks including the then young K1ZZ.
