Li-Chen Wang

In 2001 Wang was re-elected for a second term as chair of the Infrared Data Association's Technical and Test committee. In 2004 Wang was employed as Chief Technical Officer at ACTiSYS in Fremont, California, focused on IR/mobile products.

Wang also created WSFN ("Which Stands for Nothing"), a programming language for controlling robots and published by Dr. Dobb's Journal in September 1977.

Palo Alto Tiny BASIC was the fourth version of a Tiny BASIC interpreter that appeared in Dr. Dobb's Journal of Computer Calisthenics & Orthodontia, but probably the most influential. It appeared in the May 1976 Vol 1, No. 5 issue, and distinguished itself from other versions of Tiny BASIC through a novel means of abbreviating commands to save memory, and the inclusion of an array variable ("@"). The interpreter occupied 1.77 kilobytes of memory and assumed the use of a Teletype Machine (TTY) for user input/output. An erratum to the original article appeared in the June/July issue of Dr. Dobb's (Vol. 1, No 6). This article also included information on adding additional I/O devices, using code for the VDM video display by Processor Technology as an example.

Wang was one of the first to use word copyleft, in June 1976. In Palo Alto Tiny BASIC's distribution notice, he had written "@COPYLEFT ALL WRONGS RESERVED". Tiny BASIC was not distributed under any formal form of copyleft distribution terms but was presented in a context where source code was being shared and modified. In fact, Wang had earlier contributed edits to Tiny BASIC Extended before writing his own interpreter. He encouraged others to adapt his source code and publish their adaptions, as with Roger Rauskolb's version published in Interface Age.

Wang also wrote a STARTREK program in his Tiny BASIC that appeared in the July 1976 issue of the People's Computer Company Newsletter.

The first color graphics interface for microcomputers, developed by Cromemco and called the Dazzler, was introduced in 1976 with a demonstration program called "Kaleidoscope" written by Wang. According to BYTE Magazine the program, written in 8080 assembly code, was only 127 bytes long. But this short program stopped traffic on 5th Avenue in New York City.

Li-Chen Wang (born 1935) is an American computer engineer, best known for his Palo Alto Tiny BASIC for Intel 8080-based microcomputers. He was a member of the Homebrew Computer Club and made significant contributions to the software for early microcomputer systems from Tandy Corporation and Cromemco. He made early use of the word copyleft, in Palo Alto Tiny BASIC's distribution notice "@COPYLEFT ALL WRONGS RESERVED" in June 1976.
