Next to Casio, Sharp remains Japan's (and possibly, the world's) second most prolific calculator manufacturer. Like Casio, Sharp was present at the very beginning, introducing a pre-LCD programmable calculator in the mid-1970s. Like Casio, Sharp presently focuses on the educational and business markets; their current programmable models are primarily graphing calculators aimed at students. And, I am somewhat sad to add, just like Casio's, Sharp's models are also somewhat uninspiring. You won't find either the quality of a TI-89, or the functional elegance of an HP-49G in a current Sharp model.
Before handhelds, there was the Sharp PC-1001; although smaller than many handhelds, this calculator operates from AC power only. Nevertheless, it deserves mention, as it represented Sharp's first attempt to create a personal programmable calculator.
Sharp's entry into the field of handheld, battery-operated programmable calculators is represented by the PC-1201, a beautiful, well-designed, highly functional machine. Apparently this was Sharp's only non-LCD model; their next generation machine were equipped with early (yellow) LCDs, and these machines are highly sought after collectibles today. In yet another curious parallel with Casio, Sharp's first programmable model was more sophisticated, eminently more usable than many of their later programmable calculators.
Classic Keystroke Programmables
Sharp continues to produce simple low-end keystroke programmables. The technology found in the EL-5813, a 30-step machine with no program review/editing capability, has since found its way into many OEM machines as well.- Model Type Display Programming model Programming features Memory Special functions EL-5020 Scientific 10+2 LCD digits Formula programming (40 program steps) Branching 6 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-512 Scientific 10(8+2) LCD digits (127 program steps) 10 numbers Trigonometrics, Exponentials, Hyperbolics EL-5813 Scientific 8+2 LCD digits Keystroke entry (30 program steps) 7 numbers Trigonometrics, Exponentials, Hyperbolics, Standard deviation, Continuous memory No Image Available EL-7001 N/A LCD No Image Available EL-735 N/A LCD PC-1201 Scientific 10+2 VFD digits Fully-merged keystroke entry (128 program steps) Conditionals, Branching, Subroutines, Labels 12 numbers Trigonometrics, Exponentials, Linear regression, Continuous memory, Sound No Image Available PC-1300 Scientific 16 VFD characters mini-FORTRAN (256 program steps) Conditionals, Branching, Subroutines, Labels, Indirect addressing 26 numbers Trigonometrics, Exponentials, Magnetic cards PC-1300S Scientific 16 VFD characters mini-FORTRAN (640 program steps) Conditionals, Branching, Subroutines, Labels, Indirect addressing 42 numbers Trigonometrics, Exponentials, Printer, Sound, Magnetic cards
Keystroke Formula Programming
If it wasn't the first, the EL-5100 must have been one of the first pocket calculators customizable not through a "keyboard macro" style program, but by entering algebraic-looking formulae.- Model Type Display Programming model Programming features Memory Special functions EL-5100 Scientific 24 YLCD characters Formula programming (80 program steps) 11 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-5100S Scientific 24 LCD characters Formula programming (80 program steps) 11 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-5101 N/A YLCD characters EL-5102 Scientific 16 YLCD characters Formula programming (80 program steps) 11 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-5103 Scientific 12 YLCD characters Formula programming (48 program steps) 6 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-5103S Scientific 12 LCD characters Formula programming (48 program steps) 6 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory
Advanced Keystroke Programmables
Over the years, Sharp produced several programmable machines with an advanced programming model, large storage capacity, and optional extra features. The programming model used in these machines is similar to that used in Sharp's graphing calculators.- Model Type Display Programming model Programming features Memory Special functions EL-5050 Scientific 16 LCD characters Formula programming (1430 program steps) Conditionals, Branching, Subroutines 26 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-5120 Scientific 3×14 LCD characters Formula programming (1211 bytes) Conditionals, Branching, Subroutines, Labels 1211(0) bytes Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-512H Scientific 10+2 LCD digits Formula programming (256 program steps) Conditionals, Branching 13 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-512II Scientific 10+2 LCD digits Formula programming (256 program steps) Conditionals, Branching 13 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory EL-5150 Scientific 24 LCD characters Formula programming (1430 program steps) Conditionals, Branching, Subroutines 26 numbers Trigonometrics, Exponentials, Hyperbolics, Linear regression, Continuous memory
Sharp continues to have a huge lineup of pocket computers, including models that are not end-user programmable, and are sold for various business applications using preprogrammed modules.
BASIC Pocket Computers
Most of Sharp's BASIC computers look like similar models from Casio: a "landscape" look, QWERTY keyboard, and an optional numeric/calculator keypad.- Model Type Display Programming model Programming

BASIC PDAs
A unique Sharp concept: a digital assistant with a removeable "personality" module. For some models, modules containing a BASIC interpreter were available, effectively turning these machines into programmable pocket calculators.- Model Type Display Programming model Programming features Memory Special functions IQ-7000 BASIC Programmable 96×64 LCD pixels BASIC (16 kilobytes) Conditionals, Branching, Subroutines, Labels, Indirect addressing 16(0) kilobytes Trigonometrics, Exponentials, Linear regression, Continuous memory, Real-time clock, Sound
An uninspiring line of models, Sharp's graphing calculators are clearly aimed at the educational market, which is presently dominated by Texas Instruments and Casio.

Several early Sharp BASIC models, including the PC-1211 and the PC-1500, were sold by Tandy/Radio Shack as various "TRS-80" pocket computers. Lately, machines that appear to be low-end Sharp programmables have been sold under various minor (store) brand names.
