Examples of Commodore 128
The Commodore 128 (C128) was an 8-bit home computer developed and launched by Commodore Business Machines in
Here are three real-world examples of how the technology was used:
Gaming: Like its predecessor the Commodore 64, the C128 provided an affordable and accessible platform for home gaming, supporting popular titles such as Bubble Bobble, Oregon Trail, and Paperboy. Users could easily connect the C128 to a television screen and use joystick controllers to play games with friends and family.
Personal productivity: The C128 featured a BASIC interpreter that enabled amateur programmers to create and run custom applications for various tasks, such as word processing, spreadsheet management, and database creation. Software titles like GEOS (Graphic Environment Operating System) could be used to perform tasks like drawing, painting, and even desktop publishing.
Education: Thanks to its affordability and user-friendliness, the C128 found a place in classrooms as a tool for learning both computer literacy and programming languages. Students could practice programming in BASIC or even upgrade to the more advanced Z80 assembly language using CP/M mode. This exposure to computing spurred many students to pursue careers in technology.
Commodore 128 FAQ
What is the Commodore 128?
The Commodore 128 (C128) is an 8-bit home computer introduced in January 1985 as an improved version of the Commodore 64. It offers three modes of operation: C128 mode, where it operates as a fully independent computer with additional memory and functionality; C64 mode, offering backwards compatibility; and CP/M mode, where it runs CP/M operating system applications.
What are the key features of the Commodore 128?
The key features of the Commodore 128 include 128KB of RAM, expandable to 512KB, built-in BASIC 7.0 with full-screen editor, an enhanced keyboard, built-in machine language monitor, 80-column RGBI video output, and the ability to run Commodore 64 and CP/M software.
What kind of software was available for the Commodore 128?
There was a range of software available for the Commodore 128, including productivity tools, programming languages, business applications, educational programs, and games. While the native C128 library was smaller compared to the C64, the C128’s compatibility with the earlier model allowed access to a vast software library of its predecessor.
How does Commodore 128’s compatibility with the Commodore 64 work?
The Commodore 128 includes a special 64 mode that enables it to run the vast majority of Commodore 64 software. By switching to the 64 mode, the C128 turns off its additional memory and features, simulating the environment of a Commodore 64 system so that older software may run seamlessly.
What is the difference between the Commodore 128 and the Commodore 128D?
The Commodore 128D is an updated version of the original C128. It comes in a redesigned case that accommodates both the computer’s mainboard and an integrated 1571 floppy disk drive. The C128D also features a detachable keyboard, improving its ergonomics and making it more of a desktop-style computer.
