Canon Palmtronic LD-80

In 1974 Canon introduced with the Palmtronic LD-80 their first pocket calculator with the green VF-Display (Vacuum Fluorescent) and stopped the wonderful LE-series started with the famous LE-10. We remember all the calculators using the red LED-Displays: LE-80, LE-80M, LE-80R, LE-81, LE-82 and LE-100 before the LE-83, LE-84 and LE-85 settled the design line. Both manufacturing costs and operating time outdated this technology and we got the new LD-series.
