1977.

From the beginning, CBM, Commodore Business Machines, was mostly a repair shop for typewriters. CBM was offered this machine of Chuk Peddle, after he first had been given the brush off of Radio Schack. It was not really intended as a home computer, though many ended up at home anyway. Later on were many subsequent machines really beloved by the people.

At this time, there were not many processors to build a computer around and, like most others, it became MOS 6502, and 4 KB RAM. Later came 8 KB, 16 KB and 32 KB RAM. Originally was the memory, or in other words, the tape recorder, built-in. Because it was placed in front beside the keyboard, there were less space for the keyboard. It most resembled a keyboard from past calculators. Small keyboard with rubber keys was a syndrom that a number of other manufacturers also "affected" their computers with, including Sinclair. Subsequent PET-models were accomodated with an external cassette and therefor more place for a more normal and ergonomic keyboard.

Why this computer had a built-in screen depends probably on the fact, as mentioned initially, that it in the first place it was intended as a commercial product, and not for the private market. Most people at home had access to a monitor, a TV screen, to connect to. Which of course not was the case out at the industry or on the offices.
