Commodore PET was my first computer !! Record excitement every time I turned it on
The PET in a single case, which included, in addition to the computer itself (on a single board, like the KIM-1), also the power supply, keyboard, monitor, and even the recording drive. The keyboard was a "Chicklet" keyboard. The first model included 4K static memory, and firmware with Microsoft's BASIC interpreter - the first version of Microsoft for the 6502. The PET was the first of the “77 Trio” to be introduced and announced (January 77). But in practice, Commodore only started providing computers to customers towards the end of the year, after Sack and Apple Radio. PET did not have graphic capabilities in video, but its set of characters was the richest of the trio - in addition to supporting uppercase and lowercase letters (Apple and Sack Radio had only uppercase letters), also a set of 64 graphic symbols that allowed, for example, to draw tables, and even display Low-resolution graphics with the help of special "graphic characters".
Subsequent models saw changes, such as replacing the Chiklet keyboard with a standard keyboard, giving up the built-in recording drive, and increasing the memory volume.
The PET was offered for $ 600, and was also called PET / CBM, and sometimes CBM (acronym for Commodore Business Machines). Compared to the other two, its success in the American market was limited, while it was also successful in other markets, such as Canada and Europe.
