Page "Sargon (chess)" Paragraph 7

When magnetic media publishing became widely available, a Navy Petty Officer, Paul Lohnes, ported Sargon to the TRS-80, altering both graphics, input, and housekeeping routines leaving the Spracklen's chess-playing algorithm intact.

Paul consulted with the Spracklens, both living in San Diego at the time, to make the TRS-80 an instant success with the help of Hayden Book's newly established software division: Hayden Software.

Paul was not involved in further refinements to the TRS-80 version due to his reassignment to sea duty shortly after signing the deal with Hayden Software.
