Sharp

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.

Keystroke Programmables

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.

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.

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.

BASIC Pocket Computers

Sharp continues to have a huge lineup of pocket computers, including models that are not end-user programmable, but sold for various business applications and use 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.

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.
