Sharp EL-5500III: A Must-Have for Pocket Computer Collectors
The Sharp EL-5500III (released 1986) is a fascinating piece of vintage technology that effectively bridges the gap between a high-end scientific calculator and a pocket computer. Contained within a durable case protected by a sliding hard cover, this device delivers 6,878 bytes of programmable RAM, allowing students and engineers to execute complex programs on the go. Its dual nature is its greatest strength: it functions as a comprehensive, 12-digit scientific calculator in CALC mode, but flips into BASIC mode to unlock its 8-bit CMOS processor for true programming. The keyboard is highly responsive, and while the single-line, 24-character LCD might feel dated, the crisp display and solid build quality, complete with bold retro color accents, make the tactile experience of use genuinely satisfying.
What truly sets the EL-5500III apart is its advanced functionality, notably the Matrix Operation feature, which allows users to store and manipulate two matrices with support for determinants, inverses, and matrix arithmetic—a remarkably powerful capability for a pocket device of its era. This blend of scientific power and BASIC programmability captures a unique moment in computing history. For the dedicated collector of vintage pocket computers, securing the Sharp EL-5500III in excellent working condition, especially with its original packaging and manuals, makes it a rare and rewarding prize worth adding to any collection.

Beautiful Casio FX-802P in its original box.
It is a very nice example of a vintage Casio FX-802P in its original box (and manuals). Excellent condition, original AC adaptor and two boxes with thermal printer rolls. The pocket computer works. I will service the printer battery. Hopefully I will find an empty battery bay or an intact NiCd old battery and replace it with a modern alternative. Fingers crossed.
