The Casio SF-8000 — Advanced Electronic Organiser
The Casio SF-8000 was an advanced electronic personal organiser offering expanded memory and enhanced features over earlier SF models. By the late 1980s, Casio’s SF organisers had evolved into capable personal information management tools used by business professionals worldwide. The SF-8000’s larger memory allowed more contacts, appointments, and memos to be stored, making it a genuinely practical business tool that competed with the paper organisers and Filofaxes that dominated executive organisation throughout the decade.
