ML400.jpg DialPhone.jpg This category and this category in the Japanese version of my blog contains topics on the ICT equipments that I have used and related topics. The upper category is Blog from Kanada.

BTW, as shown on the top of the category page, the submission date of this page is intentionally set 0001-01-01 00:00:00. However, the actual submission date is 2009-01-18 13:58:22.

To keep the page light, I exclude photos in individual pages from the archive page. Instead, I inserted some of them here.

In 1979, i. e., when Apple II was used widely, a teacher of my high shool asked me to develope a program on Apple II. Because I wanted a program development tool, I developed a small-scale visual editor called BATE, which was written in Basic. I submitted an article on BATE to a magazine called I/O. The copyright of the article is probably owned by Kogaku-sha, but I believe it will not disturb their business by copying the article. So I put a copy here. (You can read the program list but I am sorry the article itself was written in Japanese.) If I submit an article now, I will use my real name, but I used a pen name then.

This program was my first practical program for a PC. With this editor, one can visually edit programs, i. e., one can change a text or a Basic program while looking at it. However, I had almost never used a good visual editor such as vi or emacs at that time. My favorite editor was the editor for Mitsubishi's mainframe computer called Melcom Cosmo 700. With this editor, we could edit a program while looking at about 25 lines, but it was basically a line editor. Because I mimicked this editor, one could edit a text by using commands such as "I" (Insert a line) or "C" (Change part of a line by using string matching).


I am writing on crafting a microcomputer when I was in the first year of the university. When the Intel 8080 began to be sold at Akihabara, I wanted to build a microcomputer using the 8080. Although I had never developed a digital circuit, I bought a set of the AMD 9080, a second source of the 8080, and eight memory ICs (of 1 kbit), and I dared to wire the memory circuit using a soldering iron for analog circuits and with 1-mm vinyl cables and a universal circuit board. This wiring required much more efforts than I expected. It seemed to me a miracle when the microcomputer worked. But, anyway, I inputted a very short program using 16 address-input and 8 (8-bit) data-input toggle-switches, and ran the program. The result was displayed by the 8 LEDs. It took very much time to input a program by the toggle switches, so the microcomputer soon became unused after I ran only a few programs.

Until then, I had experiences to build hardwares, such as radios and stereo amplifiers, but I had almost never touched softwares. However, in contrast, after the above experience, I seldom touched hardware but often touched software. That was because the wiring of the microcomputer was so painful, and I decided not to build hardware. I can write that this decision led to myself of these years.

I read that Steve Jobs used an expression "going to reinvent the phone" concerning iPhone in the Macworld San Francisco on January 9 this year. However, for me who intended to change the user interface of telephone drastically by a new medium called voiscape, iPhone seems to be much more conservative and it is not appropriate to use the expression "reinvent the phone".
