No problem

“After disasters like IBM’s PC Jr and the failure of PC companies like Texas Instruments and Atari, the future of home personal computers didn’t look so good. But in 1990 a new generation of home PCs brought the business back. This program looks at the products that led to this rebirth, including the IBM PS/1, the Tandy 1000, the Magnavox Headstart, the Macintosh LC and the Mac Classic. Also includes coverage of the Commodore 64 and analysis from Dataquest. Originally broadcast in 1990.”

Online shopping has its roots in 1984. At that time, an elderly woman ordered eggs, cereal and margarine from a local store.

Old times 🙂

Do you remember “how easy” was to send an email in 1984?

The large screen, lockable case, is the look of a Bondwell model 2 portable computer from 1985. This device was equipped with 64 KB of memory expandable by 256 or 512 KB, operating system CP / M version 2.2, and was able to read one-sided double-layer 3.5 ″ diskettes. In addition, this computer was equipped with a battery, which was a real feat in those days.

In today’s era, cybersecurity is essential to us. However, half a century ago, Internet 3security was not in the range. The most important thing was for the new package-based scheme to work. Protection in a harmonious team was not needed; at that time, no one had access to the network. Currently, the ubiquitous access to the Internet has caused a massive increase in the number of cyberattacks. In retrospect, it can be seen that ignoring security was a huge drawback.

A Brief History of Cybersecurity

The machine for solving systems of linear algebraic equations was recognized as the first working prototype of a specialized computer created by John Atanasoff. Inventive and unique solutions have been developed in the device. Storing numbers for use in machine calculations was a massive problem at the time. Atanasoff used capacitors to store the electric charge for his project, which was able to represent numbers in the form of logical zeros and ones. The capacitors were mounted on rotary bakelite cylinders with metal strips on the outer surface. Each cylinder could store thirty binary numbers that were read from metal belts at cylinder rotation.

In the world of computers, some terms are sometimes used in a surprising way, such as the expression “Personal Computer”. For example, the IBM 610 Auto-Point computer (from 1957) was described as “the first IBM personal computer” because it was designed to be operated by only one operator, but this machine was not based on the concept of program memory and it cost $ 55,000! Other candidates are LINC computers from MIT (1963), Datapoint 2200 from CTC (1971), Kenbak-1 (1971) and Xerox Alto (1973), but all of these machines were either incredibly expensive, relatively useless, or were only experimental designs .

In 1973, IBM presented a device with a not very sophisticated name – IBM Special Computer APL Machine Portable, or IBM SCAMP for short. And although SCAMP never went into mass production, it was based on a computer that could be considered the first portable computer in history – IBM 5100. Unfortunately, it did not offer much beyond its portability, and even here it could be accused of much.

In 1968, Alan Kaya of Xerox PARC published the “Dynabook” document. The device presented in it was only an idea; it was not among the products that were to be sold. The project was described in detail by a Xerox employee or a compact device with its battery, hard disk, wireless connection, screen, and keyboard. The device had access to office, educational, entertainment, and multimedia applications. The purchase cost was to be very low, not just $ 500. Unfortunately, the project was not implemented and did not match the size of the existing machines, which were the size of the cabinet. However, despite everything, I will call this project visionary because it was only less than half a century later.
