GLENVIEW, Ill. (AP) _ Zenith Electronics Corp. said Monday it will stop making high-resolution monochrome computer monitors in Taiwan and shift assembly of the units to Mexico, eliminating 600 jobs in Taiwan.

The restructuring of Zenith Taiwan Corp. into a purchasing operation will begin in April, Zenith said in a statement. The manufacturing subsidiary employs about 625 people, Zenith spokesman John I. Taylor said.

The Zenith Taiwan unit will become a buyer of high-resolution monochrome picture tubes and other components destined for assembly in Mexico. A Taiwanese company, Techware Electronics Corp., will supply Zenith with fully assembled low-resolution monochrome computer monitors.

''Zenith plans to maintain a considerable amount of business in Taiwan, sourcing millions of dollars of monochrome picture tubes and other components there annually,'' Charles J. Sindelar, president of Zenith's display division, said in a statement.

The Glenview-based company said it planned to consolidate assembly of high- resolution monochrome monitors with its color monitor assembly plant in Mexico.

Zenith, the only U.S.-based television maker, announced last month it will shift its remaining U.S. television assembly operations from Springfield, Mo., to two locations in Mexico next spring.
