Greetings to you, my young inquisitive and creative reader. I am very pleased with our meeting on the pages of the blog, which is dedicated to the additional education of children and young people.
My name is Victor, pseudonym Pykhtelkin. On the pages of the blog will be offered important options: information and practical benefits. The purpose of a blog is simple – to help young readers in their studies and in life, thereby achieving high blog attendance on my topic.
I will try to convey the content of articles and exercises with great love for the young inquisitive reader, using only personal experience collected since October 22, 1982. If material from other sources is used, there will necessarily be links to those sites or books that the reader can find on the internet.
On October 22, 1982, due to circumstances, i first mastered the Wang 2200 MVP BASIC interpreter of the American software-controlled computer TRS-80, a Russian copy of the Iskra 226. Since then, i no longer separate from computers to this day and work on them daily. Now i have personally assembled three system blocks that are interchanged monthly. The fourth computer in reserve for suddenly arising tasks and experiments. At that time, I could not even dream of a personal computer, since one hour of work on a machine was then worth 95 cents.
To solve the problems of mathematical regression analysis, it became necessary to process files directly by interpreter commands: open a file, write to a file, close the file. Despite the absence of a file operating system, at that time, the Iskra 226 was a very powerful computer that allowed solving a large amount of tasks with completing the results of calculations not only in text mode with documentation on the printer, but also graphically – with a graphic plotter.
The 14″ black-and-white (14 B/W) monitor was made in a single package with the calculator unit. The keyboard was already a separate unit. A number of function keys F00-F31 were located horizontally on top of the keyboard. Mouse manipulators, 3.5″ floppy disks and optical compact discs were not yet invented. There were 8″ single-sided floppy disks, which after modification became double-sided with an increase in capacity by half.
Expressing deep appreciation and gratitude to the talent of the American engineer WANG, i have to mention the disadvantage of the TRS-80 computer – this is a closed architecture. The keyboard did not consist of letters, but from the names of interpreter operators Wang 2200, for example, by pressing only one key: “PRINTUS” the entire result of calculations was displayed in the form of a table to print.
Expanding the concept of open architecture is beyond the scope of this article. It will be considered later if it will be interesting for young blog readers.
All materials and recommendations for reading and guidance relate primarily to those readers whose computer configuration coincides with mine: Windows XP SP3, monitor 19″ (3×5), screen resolution 1024×768 pixels or android device with a screen diagonal of 6″ (16×9), the screen resolution is 2160×1080 pixels.
If your configuration is different, it is expected, from the one i have given, then you have two choices – continue reading blog articles and perform exercises for your configuration or go to my competitors on this search query.
Kind regards, blogger Pikhtelkin.
