Commodore 8032-SK is a computer in the PET series from Commodore. Internally, it is a PET 8032 but which has been updated with a new case design and a separate keyboard (hence "SK"). The machine was also sold in Europe (Sweden) as the "PET 200"

Case

The case design had originally been intended for the PET's successor: the "CBM-II" series but after it had flopped in the market Commodore instead reintroduced the PET series using the CBM-II's case designs.

The case was designed by Commodore employee Ira Velinsky. The design-firm Porsche Design had been consulted by Commodore but their design had been deemed too expensive too manufacture. Velinsky's design for the CBM-II supposedly won a design award ^{[Citation needed]}.

The CBM-II's keyboard has a function key row, where the 8032-SK's keyboard has empty space.

Description

The keyboard unit was provided by Mitsumi. The switch type can be considered a variety of the Mitsumi hybrid switch. The alternate action shift lock keyswitch is a Futaba linear lock, mounted sideways. The Commodore 64 did use a Mitsumi switch for shift lock, but it was not a keyboard switch; it was not until the Commodore 64C that the shift lock key used a proper keyboard switch that could be soldered to a PCB, after Mitsumi standard mechanical had been introduced to market.

The keycaps are double-shot moulded, and use Microgramma/Eurostile for the legends. The keycaps are hollow inside — they are designed to snap onto adapters that provide the desired keycap mount. One adapter type is used with the Mitsumi switches, and another adapter type is used for the single Futaba switch.
