Brady =========================================== ---------------- THESIS ABSTRACT A course was designed to teach Top-Down programming to second level students who had no previous computer experience. The purposes of the course were a) to enable them to become computer literate and b) to develop their problem-solving ability. The course was designed to teach programming in a manner which was independent of any particular programming language or machine. This approach was prompted by dissatisfaction with traditional courses which generally concentrate on the syntax and semantics of a particular programming language, at the expense of developing important underlying concepts.

  • Atari's ST and the Amiga from Commodore. Three Ispuggers
    The new 68000 machines are out— Atari's ST and the Amiga from Commodore. Three ISPUGgers have bought ST's with color monitors for $995; all report they are unable to penetrate below the Mac-like GEM interface, access the 68000, or use the underlying operating system. As with the C64, the computer is in the keyboard enclosure with 512K bytes of RAM. A separate power supply is required for the computer and for each disk drive. With the two-button mouse and two drives, you must cable together eight separate units. Have a large desk and a tolerance for a warren of cables. Two users report they don't like the mouse; at least you have an option with the ST; unlike Macintosh, it provides cursor con­ trols on the keyboard. Atari, short of money, is trickling the machines out to dealers and supporting it with what little advertising it can afford. The single cutesy wee 3.5-inch disk holds 360K bytes, which in the day of 200K byte programs and megabytes of data is about as useful as a glass of spit at a four-alarm fire. Atari has repeated Apple's bitter mistake with the Mac, but will, we hear, offer a double-sided 720K byte wee drive for more money. Apple, of course, is upstaged. Its main act, the 512K byte Fat Mac, has no color and costs twice as much; its aging ballerina, the Apple II, can compete neither on performance nor price. Apple has a year, perhaps two, to arrange a new act and to reduce its always-high prices, until the ST attracts enough support to compete against Apple in software.

    BASIC - Wikipedia, the free encyclopedia 1/22/12 1:10 PM BASIC From Wikipedia, the free encyclopedia BASIC is a family of general-purpose, high-level BASIC programming languages whose design philosophy emphasizes ease of use - the name is an acronym from Beginner's All-purpose Symbolic Instruction Code. The original Dartmouth BASIC was designed in 1964 by John George Kemeny and Thomas Eugene Kurtz at Dartmouth College in New Hampshire, USA to provide computer access to non-science students. At the time, nearly all use of computers required writing custom software, which Screenshot of Atari BASIC, an early BASIC was something only scientists and mathematicians tended to language for small computers do. The language and its variants became widespread on microcomputers in the late 1970s and 1980s, when it was Paradigm(s) unstructured, later procedural, typically a standard feature, and often actually built into the later object-oriented firmware of the machine. Appeared in 1964 BASIC remains popular to this day in a handful of highly Designed by John George Kemeny and modified dialects and new languages influenced by BASIC Thomas Eugene Kurtz such as Microsoft Visual Basic.
