The mcm/70 is a type of computer that was used back in the olden days, when technology was much simpler. It was kind of like a big box full of different parts that all worked together to help people do things on the computer.
Think of it like a toy tool set with lots of different tools, like a hammer, screwdriver, and wrench. Each tool does a different job, but they all work together to help you fix or create something.
Similarly, the different parts of the mcm/70, like the central processing unit (CPU), memory, and storage, all worked together to help people use the computer for different tasks, like writing documents or doing calculations.
While the mcm/70 may seem outdated now, it was a big deal back in its time, and helped pave the way for the more advanced technology we use today.
