Those who recall the company’s announcement back in April 1986 that it was abandoning the volume chip business and reducing its involvement to a chip design lab and a prototyping line (CI No 421) may feel a touch of deja vu about Data General’s news late last week that it would phase out its chip operations. Seems that pilot line was rather more substantial than the company implied, because the 1986 move cost only 75 jobs at the Sunnyvale plant, whereas 150 will go by the end of the year this time. Chip design activity is unaffected.
