The Commodore 64G (also C64G, C=64G, C 64 G) is an 8-bit home computer produced by Commodore Business Machines since 1987. It is a particular version of the Commodore 64, intended for the German market. It should not be confused with the Commodore 64 ALDI, which was intended for a supermarket chain.

The Commodore 64G has the same shape as the first version of the Commodore 64, called breadbin. The case, however, is white, with a white keyboard. Contains the motherboard of the Commodore 64C.

This Commodore 64 entered the collection, along with a batch of other vintage material, in September 2021. They gave it to me in exchange for a repair. The gift was much appreciated!
