The Japanese FM Towns computer and game console is named in his honour.
The name "FM Towns" is derived from the codename the system was assigned while in development, "Townes"; this was chosen as an homage to Charles Hard Townes, one of the winners of the 1964 Nobel Prize in Physics, following a custom of Fujitsu at the time to codename PC products after Nobel prize winners.
