Jumbo line (1988–1992)

The latter called for standardization in the use of such compression algorithms in hardware, as to ensure cross-compatibility between different manufacturers and to prevent unreadable backups when proprietary hardware becomes obsolete.
The company's Jumbo line eventually comprised the majority of the company's sales and was instrumental in its success into the early 1990s.
By May 1990, Colorado Memory Systems had split from its parent company Colorado Time Systems while still operating out of Loveland. Their headquarters spanned 88,000 square feet and employed between 250 and 500 workers, each in disparate divisions, including management, manufacturing, and software development.
By late 1992, the company employed 600.
