strange programmable on ebay

[badaze]

I have a Sharp PC 1253 which is like the PC 1270 but based on a PC 1251. It uses an astrology program. Mine almost works after nearly its 30 years old. I write almost because it shows errors when I run the program but there’s still the program in it. Anyway, as you wrote, without a program, it is a basic 4 function calculator unable to do calculations over 8 (or 10) figures.
