Commodore Plus/4 Physical Dimensions and Case Size

The Commodore Plus/4, released in 1984, remains a notable piece of computing history known for its integrated software suite and distinct industrial design. Collectors and enthusiasts often seek specific hardware details for restoration, display, or shipping purposes. This article provides the exact physical dimensions of the Commodore Plus/4 case, along with context regarding its design form factor compared to its contemporaries.

Exact Case Measurements

The physical footprint of the Commodore Plus/4 is consistent with the standard home computer form factor of the early 1980s. The case dimensions are generally accepted as follows:

• Width: 460 mm (18.1 inches)
• Depth: 200 mm (7.9 inches)
• Height: 65 mm (2.6 inches)

These measurements include the main plastic housing but may vary slightly depending on whether the rubber feet or protruding ports are included in the total count. For most shelving and enclosure projects, using the width of 460 mm and depth of 200 mm ensures adequate clearance.

Weight and Form Factor

In addition to linear dimensions, the weight of the unit is a critical specification for handlers and collectors. The Commodore Plus/4 weighs approximately 2.4 kg (5.3 lbs). This weight contributes to the stability of the keyboard during typing, a common design priority during that era of computing. The low-profile height allows the machine to sit unobtrusively on a desk, typically beneath a monitor or television set used as a display.

Design Context

The case design of the Plus/4 was intended to be sleeker than its predecessor, the Commodore 64. It features a dark grey chassis with a lighter grey keyboard section, distinguishing it visually within the Commodore lineup. Understanding the dimensions helps in appreciating the engineering constraints of the time, where fitting a motherboard, power supply, and keyboard assembly into a compact plastic mold required precise planning. These specifications remain essential for anyone looking to preserve the hardware in its original condition.
