Prinztronic Scientific 3001M
Brief History
Dixons offered a wide variety of pocket and desktop calculators under the Prinztronic brand name. Taiwanese Qualitron produced some Prinztronic calculators which can easily recognized for unique design: the low-end converter, financial or scientific models to the most complicated programmable variations. The Prinztronic Scientific SC3001M are identical to Qualitron 1445 with its uncommon keyboard layout used Rockwell A4001 circuit which lacks exponential notation and give poor calculation precision. Qualitron produced calculators using almost the full spectrum of Rockwell’s chips and take advantage of identical pinout: most models used identical printed circuit.
