The Commodore SX-64 Executive was the technological forerunner of its time and a complete business failure, despite being the first color portable computer following in the footsteps of history’s most profitable computer (the Commodore 64)only 85,000 were made over its cut-short 2-year production. The SX-64E’s failure eventually resulted in Commodore shuttering all its operations 11 years later in 1994 1

It is clear through the analyses of online databases, archives, and secondary source documents that the numerous shakeups Commodore underwent in 1984, namely Commodore’s founder Jack Tramiel leaving after falling out with Irving Gould the company chairman and the Commodore Plus/4’s lackluster sales and performance. Leading the SX-64E, the first color portable computer with the best performance of the time, to be a mismarketed failure as it was targeted towards businesspeople (despite its lack of business-related software) rather than as a gaming platform (with over 10,000 titles) 2.

The departure of Jack Tramiel from Commodore left it without a cohesive vision, Commodore no longer understood the technology they were selling which prevented them from investing in new product lines that could fulfill the needs of their customer base. Commodore struggled for years with limited success against Apple’s user-centered Macintosh computers and IBM’s business-focused computer line, only to financially collapse in the 90s competing against Jack Tramiel’s new company Atari Computers.
