La Divisumma 24 fu la rivoluzione nel calcolo a supporto degli uffici in Italia perché fu il primo apparato a larga scala a consentire le 4 operazioni, invece che le usuali somma e sottrazione.
L'Istituto Tecnico Statale "Buonarroti" nacque nel 1963 come Istituto Tecnico per Geometri "Buonarroti". Grande fu l'attenzione del preside prof. Michele Scaravilli sin dalla istituzione per dotare la scuola di apparati di calcolo scientifico, di apparati e macchine per l'ufficio (macchine per scrivere e calcolatrici da tavolo) e di supporti multimediali alla didattica (cineproiettori, audio registratori-riproduttori a nastro, fonoriproduttori, radio, televisori, etc.).
