This CBM is a successor to the Commodore PET, it has a bigger keyboard and 32KB dynamic RAM memory. The larger keyboard means that the first cassette drive now has to be an external unit.
Although the keyboard is a more conventional size than the original PET, it still retains the PET's quirky arrangement. Characters such as ", $, (, *, etc, which are normally shift characters, are typed directly on the PET. The shift key either produces Commodore's graphics set or lower-case characters, depending on a bit pattern set in the peripheral control register of the 6522 Versatile Interface Adaptor chip. Infuriatingly, the keyboard lacks a CONTROL key.
