SHARP EL5120 Programmable Scientific Calculator: SOLVER machine with ENTER key?
Compact, well built, direct algebraic logic calculator, with a handy uncommon 3 lines alphanumeric characters with very high contrast black LCD display, from 1994.
Obviously the SOLVER capacity is the main feature of the model complemented by its programming ability. I didn't spend my time checking it in detail, but here are some highlights taken from the manual: Powered by a single CR2025 battery cell. 3mW power consumption at 3VDC. Contrast adjust by software. Display: 14 characters and 2 exponents x 3 rows, 5x5 dot matrix. Number of display digits: 10 mantissa + 2 exponent Number of internal calculation digits: 12 mantissa Variables:
Memory manager shows free memory. Memory is shared between Variables, Programs and Equations. Each variable consumes 8Byte (where its name takes 1Byte). Each new Program structure takes 32 Byte; each line takes 3Byte plus the number of characters (1Byte each) or commands (1Byte each). Setup allows to chose Deg, Rad, Grad, Floating, Fixed, Scientific, Engineering, Fractions. It has four Operation Modes:
It supports three ways to calculate an unknown variable concerning its SOLVER calculation methods:
