Calculator de birou Olivetti SUMMA 14

Recommended Posts

Am intrat în posesia unui vechi calculator de birou - Olivetti SUMMA 14 - căruia însă-i lipseşte transformatorul de alimentare.Poate mă ajută cineva cu datele pentru tensiunile din secundar, pentru că primarul e alimentat cu 220V.Presupun că este vorba de 2 tensiuni, una pentru alimentarea circuitului integrat Toshiba TC83220şi alta pentru afişorul cu tub fluorescent.Mulţumesc anticipat.
