it says is among the most powerful available for use as a "server'' connecting a network of PCs.

The new machine will run three times faster than IBM's current top-end PCs in computer network uses, the company said.

The PC also features an error-correction system that IBM, the world's largest computer maker, says protects users from most memory errors.

IBM, whose local dealers are the Computer Centre, said the new processor enhances the performance of its PS/2 Models 90 and 95 XP 486 systems, and demonstrates the company's commitment to technology leadership and investment protection.

The common processor complex design of these systems helps protect the user's original investment by allowing a significant performance upgrade in server applications and computer capabilities, the company said.

In October, 1991, IBM announced the fastest 386 SX performance in the industry available as an upgrade in its midrange product line. The 386 Slc upgrade was to give a performance boost of up to 88 percent.

Then in February this year, the company announced the integration of that with the Personal System/2 Model 56 SLC, 56 SLC LS, and 57 SLC.

The computer will be sold in three models that are priced up to $29,850.

IBM, in a radical departure from its marketing practices, announced yesterday it will sell some personal computers directly to consumers.

A company spokesman said IBM would sell its low-end PS/2 models, the 35 and the 40, through an 800 telephone number.

IBM has traditionally sold its computers only through dealers.

Rival Digital Equipment Corp. recently set up a mail-order operation to sell its PCs and industry sources said yesterday that Compaq Computer Corp. is also moving toward direct sales.

The industry giants are aiming for part of the market controlled by smaller companies such as Dell Computer Corp., one of the leaders in the direct-sales field.

IBM has recently been trying to boost sagging revenues in its personal computer business, which dropped 10 percent last year.

In a major reorganisation announced late last year, IBM gave its PC unit greater autonomy in setting its marketing policies. The division now has greater control over pricing, which has become much more competitive than previously.
