Electronics firms are moving to revamp their personal computer operations as sales continue to dwindle.

Domestic shipments of PCs in the April-September first half of fiscal 2002 slipped 10 percent from a year earlier to 4.555 million units, according to the Japan Electronics and Information Technology Industries Association.

The number led the association to revise downward the shipment projection for all of fiscal 2002 through next March 31 to roughly 10 million units from the initial forecast of 11.1 million.
