What Was the Weight of the Commodore Plus/4 Unit?

This article provides a detailed look at the physical specifications of the Commodore Plus/4 home computer, released in 1984. It focuses specifically on the hardware dimensions and mass of the main console, excluding external power supplies and connectivity cables. Readers will find the exact weight measurement of the unit alone, along with context regarding its portable design compared to other systems of the era.

The Commodore Plus/4 was part of Commodore International’s 264 series, designed to be a cost-effective successor to the popular Commodore 64. One of the defining features of the 264 series, which included the Plus/4, the Commodore 16, and the Commodore 116, was a compact form factor intended for both desktop and casual use. When evaluating the hardware for transport or desk setup, the physical mass of the computer is a key specification for collectors and enthusiasts.

The weight of the Commodore Plus/4 unit without peripherals is approximately 1.2 kilograms (2.65 pounds). This measurement accounts for the main case containing the motherboard, keyboard, and integrated ROM cartridges, but it does not include the external power brick or any RF modulator cables. This relatively light weight was achieved through a streamlined plastic casing and the integration of software into the system ROM, which reduced the need for additional external hardware during operation.

In comparison to its contemporaries, the Plus/4 was considered quite lightweight. The external power supply unit added additional weight to the total setup, but the core computer remained easy to move. This specification remains consistent across most technical datasheets from the mid-1980s. For modern collectors verifying the completeness of a hardware set, knowing the base unit weighs around 1.2 kg helps distinguish the main computer from bundled accessories or packaging materials.
