In 1977 a Dutch group of enthousiasts, with professional background in electronics, mainframe software, general interest in microprocessors and students started a community around the then new KIM-1. Other 6502 based SBC’s like the SYM-1 and AIM-65 were also targeted, but in the beginning it was mostly a KIM-1 club, hence the name KIM User Club.
After 1980 a large grow in members, at least 500 active in 1984, due to the availability in diy format of a KIM-1 clone, the Junior of Elektuur/Elektor.
The club developed a variation of the Octopus/EC65 bus based system of Elektuur, called DOS65. With its inhouse developed floppy controller and the DOS65 operating system, it was a capable system. Several hundreds must have been build, I own several.
The ‘Stichting’ (Foundation, organization without profit) called “KIM Gebruikers Club”, was founded January 1977 and the publications were published until 1995. I was chief editor of the magazine from 1978 to 1982, issues 11 to 20, and member of the board until 1983.
