Creative Micro Designs (CMD) was founded in 1987 by Doug Cotton and Mark Fellows. It is a computer technology company which originally developed and sold products for the Commodore 64 and C128 8-bit personal computers. After 2001 it sold PCs and related equipment.


CMD's first product, JiffyDOS, was developed from 1985 onwards by Mark Fellows. An updated disk operating system, it maintained broad compatibility with Commodore floppy drives' DOS while offering much increased read write access.

CMD stopped selling Commodore products in 2001. In July of that year, programmer Maurice Randal was sold an exclusive license to produce and sell the Commodore related products. His company Click Here Software Co supplied the products until around 2009.[1]

In 2010, Jim Brain acquired the license to supply JiffyDOS. Since January of that year, he has sold the product via his web shop Retro Innovations.
