Commodore 128DCR

The C128DCR was a cost-reduced metal-cased redesign of the 128D with revised integration and expanded VDC video memory.

It was the final major production form of Commodore’s 8-bit computer line.

Notable Features

• The metal chassis and lack of carrying handle distinguish it from the plastic 128D.
• Later integration and 64KB VDC memory improve 80-column use.

Historical Significance

• It was the final major production form of Commodore’s 8-bit computer line.

Collector’s Notes

• Board revision, regional video standard, power supply, keyboard legends and original accessories should be recorded.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
