3 August 1993 Apple introduced first PDA — the Newton MessagePad. The exhibition Expro Macworld in Boston, the company, which at that time was headed by Gil Amelio, showed a revolutionary gadget — electronic organizer with touch screen and handwriting
The first version of the device worked on a processor with a modest 20 MHz, had 4 megabytes of RAM and only 640 kilobytes of persistent storage, and worked from the four “mizinchikov” batteries. Just before 1997, we managed to produce 14 models (including several made for third parties), the latter of which was almost ten times more powerful.
With the appearance of the gadget Steve jobs, who was then in “exile”, hated it, something that was not mention in the interview. But the main claim to the development refers to the need to use a stylus pen, computer pen. After returning to company, jobs immediately closed the project:
“God gave us ten styluses, and there is nothing to invent another one. If not for the critical situation in the Apple, I would personally bring to mind this thing. But I don’t trust people who was involved in it. My gut instinct is that technology is not bad, but incompetent managers ruined it. Covering the project, I released some good engineers who could work on new mobile devices. Their experience was helpful to us when we switched on the iPhone and iPad.”
3 August 1960, held the first telephone conversation via the moon. In those years, scientists at Bell Laboratories experimented with artificial satellites, is a passive container of thin films with an aluminum coating mirror, which simply reflects the signal in the desired direction. It provided communication between distant points, for example, on different continents. But in one experiment the relay acted as a natural satellite, the Moon. However, in practical application, the Moon was not so convenient due to loss of signal and situation.
Balloon relays also proved to be useful not only ensure the line between the United States and the Soviet Union, but also to explore the upper atmosphere. These huge “balls” had a great sail and fly in low orbit, why time was slowed down on the air particles.
It should be clarified that the experiments in “Moon bounce” (a name given to a series of experiments) were conducted from November 1959, but only 3 August 1960 scientists told the press about uspeha
August 3, 1977 Radio Shack introduced the TRS–80 Model I — one of the most popular computers of the era. He was executed in the format monobloco, that is, the motherboard contained in a single housing with keypad — a common decision then. Monitor and recorder, which reads the programs from the cassettes supplied from the set — a complete set was worth $ 599. This product was the most expensive of all that were sold in network Radio Shack, so for starters made only 3000 devices — the same number of stores numbered network. The calculation was that if the computers would not have to buy up, then you can use them for your own accounting needs.
TRS–80, who was given a middle name offensive Trash–80 (“Trash–80”), was built on an 8-bit Z80 processor with a frequency of 1.77 MHz — the same chip used in dozens of other models, including the iconic ZX Spectrum computer and games console Gameboy. The base model was supplied with only 4 kilobytes of memory, but then there were versions with 16 KB on Board. The monitor was a modified 12-inch TV and displayed a black-and-white image, containing 16 lines of 64 characters per line.
Despite fears, TRS–80 proved to be extremely popular. For the first month managed to sell 10 of thousands of computers, and the total sales for the four years amounted to $ 250 thousand.
