Back-up tape subsystem and local area network server manufacturer Tallgrass Technologies Inc of Overland Park, Kansas, has agreed to be acquired by CMS Enhancements Inc of Tustin, California, on undisclosed terms. CMS – it appears to stand for Complementary Microcomputer Storage – is a storage subsystem integrator that presently buys all its hardware from the likes of Seagate Technology, Cipher Data and Archive Corp. It is pitching for $100m in sales this year, whereas Tallgrass sales have reportedly slumped from the $50m it did in 1984. CMS wants Tallgrass for its tape and server technology and manufacturing, and plans to continue to run the it under its own name.
