TouchStone Software Corp, Huntington Beach, California-based publisher of the CheckIt diagnostic software, has added a new version, the CheckIt Floppy Drive Testing System, designed to check that 5.25 and 3.5 floppy drives are correctly aligned and whether various other mechanical functions are working properly, helping users to avoid potential disasters resulting in the loss of data; alignment is tested using the patented Mini-Spiral disk, made for TouchStone by Asky Inc, and the system is already used in personal computer manufacturers’ quality assurance and repair departments; it costs $70 for either size disk, $100 if you want both, but introductory pricing will be $50 and $80 until March 31 1991.
