This 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.
This meaty 16-page excerpt from BYTE V6N1 January 1981 includes the Editorial, "The Hand-Held Computer" and the very interesting full article "The Panasonic and Quasar Hand-Held Computers - Beginning a New Generation of Consumer Computers".
The article discusses at great length these two models and ends with 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.
All three models are featured on the front cover. As far as I remember, the Panasonic and the Quasar (virtually the same model), even though more powerful and sophisticated, failed to make much of an impact, while the comparatively modest 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 nor 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.
The Sinclair Research ZX80. The new ZX80 microcomputer from Sinclair Research Ltd is a remarkable device. Although first announced to the North American public in February, 1980, the microcomputer did not become available until the fall.
During the wait, the price has dropped from the expected $245 to just under $200. Because of this, the ZX80 is being widely advertised as the first personal computer for under $200. Can it be any good if it sells for under $200 ? This is a reasonable question, but the question that is most important when buying a computer is, “Will it do the job I want it to do ?”

At the beginning of 1981 I bought a Sinclair ZX81, a true computer at last (not a slow pocket computer or even slower glorified calculator,) which I could program in a nice version of BASIC and, most importantly, in Z80A machine language. I could also connect it to a TV for a full-screen 24-line display (not a puny 1-line/4-line LCD one,) to create and run fast video games.
To complement it and learn the tricks of the trade as fast as possible, I subscribed to INTERFACE, a very nice monthly magazine full of all kinds of programs, code snippets, tricks, the works !
Even the adds were mostly very interesting and I bought a number of the products offered (including the book reviewed in this issue, "The Soul of a New Machine",) so here you are, a full 24-page issue for you to see how exciting it all was, kinda PPC in its good times.
INTERFACE - The monthly magazine for ZX80, ZX81, Atom and BBC Microcomputer. March 1982, Volume 2, Issue 7
INSIDE THIS ISSUE :
