CAMBRIDGE, Mass.--Compaq Computer will open a new bioinformatics solutions center here within six to nine months, Ben Rosen, Compaq's chairman, announced last month. Compaq hired Nat Goodman, who was until recently a senior scientist at the Jackson Laboratory, to direct the center. The facility, which Goodman predicted will house a "formidable-sized" staff, will be operational around January, the company said. An exact location has not yet been chosen.
