A testimonial on computers from the 1950s/1970s
During the 1950s and 1970s, computers were still relatively rare and expensive, and they were primarily used by businesses and universities for complex calculation tasks. For an individual, owning a computer was an inaccessible luxury.
Computers of that era were massive and heavy, with dimensions sometimes comparable to those of a car. They generally consisted of several printed circuit boards, numerous vacuum tubes, and several external hard drive units. The memory of these computers was very limited, with only a few kilobytes of RAM, and they were not capable of processing data in real-time as modern computers do.
The programming language used on these computers was binary, which consisted of a sequence of 0s and 1s. To use these computers, it was therefore necessary to know binary language and be able to manually type lines of code.
Binary language is a programming language that consists of a sequence of 0s and 1s. It is used by computers to process data and execute instructions. Here is an example of binary code that could have been used in a computer from the 1950s/1970s:
10101010101010101010101010101010101010101010101010101010101010101
This binary code represents a sequence of instructions that could be used by the computer to perform calculations or process data. To use this code, one had to know binary language and be able to manually type these instructions on a specialized keyboard.
It is important to note that binary language is still used today in modern computers, but it is generally hidden from users and is automatically converted into a more user-friendly programming language, such as C++ or Java. However, computers of the 1950s/1970s required an in-depth knowledge of binary language to be used effectively.
This made using these computers very complex and reserved for computer experts.
Despite these limitations, these computers were at the origin of many technological advances and played a crucial role in the development of modern computing. Notably, they allowed for the development of database management software, the creation of real-time production management systems, and the establishment of large-scale communication networks.
Today, computers have become common devices accessible to everyone, but it is interesting to remember the incredible evolution these devices have undergone over the last decades. Computers from the 1950s/1970s paved the way for modern computing and contributed to the creation of many technological innovations that have profoundly changed the way we live and work.
Here is a list of computer models from the 1950s/1970s:
- IBM 701: The first computer marketed by IBM in 1952, it was primarily used by universities and governments for complex calculation tasks.

- UNIVAC I: The first commercially available computer in the United States, it was launched in 1951 by the UNIVAC (UNIVersal Automatic Computer) company.
- IBM 650: Launched in 1953, this computer was intended for universities and businesses and was capable of processing up to 10,000 instructions per second.
- IBM 1401: Launched in 1959, this computer was primarily used by businesses for the management of their financial data and production operations.
- DEC PDP-8: Launched in 1965, this computer was primarily used by universities and governments for complex calculation tasks.
- IBM System/360: Launched in 1964, this computer was primarily used by businesses for the management of their financial data and production operations.
- DEC VAX: Launched in 1978, this computer was primarily used by universities and governments for complex calculation tasks.
It is important to note that this list is not exhaustive and that there are many other computer models from the 1950s/1970s that played an important role in the history of computing.
