Lars Karlsson,
a Swedish electrical engineer, computer scientist and technologist, in 1970 founder of Dataindustrier AB ^[1], which had the card computer Data Board 4680 as first product, incorporating an Intel 4004, a Motorola 6800 and an Intel 8080, later eventually a Zilog Z80 ^[2]. Starting in 1977, within about one man-year, Karlsson wrote a chess program in Z80 assembly for that card computer, dubbed Rook. Rook 4.0 played a strong WMCCC 1980, and Rook 4.5 lost from Boris Spassky during his simultaneous exhibition at the 1981 CeBIT fair in Hanover, Germany ^[3].
