Sharp Pocket Computers

Sharp Raw Scans

Section features scans I've made of assorted documents other than Pictures or Brochures, such as booklets or bulletins. Most are part of my Project HAM, i.e., scans of 40+ year-old vintage documents not authored by me but which were sent to me back then, and due to their perceived rarity (even uniqueness right now) I'm making them available here.

I scanned most paper documents at 300 dpi, resulting in hi-res 2,552 x 3,508 PNG images, which were then converted to multi-page PDF documents with embedded OCR'd texts (e.g.: to allow for copy/paste operations). Some of them also include text pages with my own Notes, providing background info and extra details.

PDF SHARP Raw Scan - BYTE V6N1 January 1981 - SHARP PC-1211 (Full Scan)

This color excerpt includes a nearly full page on the TRS-80 Pocket Computer (aka SHARP PC-1211), which includes a description of what tasks each of its two 4-bit microprocessors are assigned to, and other interesting details.

The SHARP PC-1211 gave rise to an extremely successful and extended family of ever-improving Pocket Computers, which became very popular in Japan and Europe (Germany in particular.)

Last but not least, the excerpt also includes another article, "Numerical Analysis for the TRS-80 Pocket Computer", which features a discrete-Fourier-transform program, and another program that computes the time-domain response of a system with a given transfer function.

PDF SHARP Raw Scan - History of Pocket Computers 1980-2000

(8 pages, original document, not a scan)

An article by Roland J. Saam, Life Senior Member IEEE.

Pocket computers are a category of personal computer. A complete computer system in a small battery powered package that slips in your pocket, it has all the elements needed for writing and running programs. They are reliable, affordable and useable by persons with minimum knowledge. Applications benefit from quick, on-the-spot data gathering, validation, analysis. Learning to program was simple and easy with the manuals supplied with them.

P.S.: Endnote #4 includes a reference to one of my articles: "An informed comparison of the PC-1211 to the Hewlett-Packard HP-41C programmable calculator was written by Valentin Albillo, 'Know Thy Foe: A New Contender'."

PDF SHARP Raw Scan - PC-1360 Schweizerische Armee TopoRechner (Full Scan)

(28 pages, in German)

This is the Instruction Manual for a bundled system composed of a SHARP PC-1360 pocket computer, a 16 Kb RAM Card containing proprietary software, the corresponding documentation and a sturdy carrying case with inside foam to protect it all in rough terrains and atmospheric conditions. The software seems to deal with topographic calculations needed for the operation of Swiss Army's mobile artillery units back in 1986.

These dedicated systems were eventually decommissioned and many ended up in eBay, where they were auctioned at very low prices. Myself, I got no less than five of them, complete with sturdy case and all, at around 50€ each, a bargain for such a powerful vintage 4-line, graphic LCD unit with 16 Kb RAM card and all.

The Sharp 1211 pocket computer was introduced two years ago. Since then there have been considerable developments in the microcomputer field and to keep pace SHARP has introduced a new pocket computer, the PC-1500, a more powerful and easier-to-use version with some intriguing accessories.
