I.B.M. to base a computer on powerful i486 Intel chip

Article Abstract:

IBM will use the Intel i486 microprocessor in its new version of the PS/2 70 to create the PS/2 70 486 microcomputer. IBM offered an upgrade kit for the original PS/2 70, the 486/25 Power Platform, but the kit was pulled from the market after a design flaw was found in the microprocessor. The PS/2 70 486 is basically a repackaging of the original 70 with the 486/25 platform added. The PS/2 70 486, starting at $12,395, is intended for users who require particularly high performance. The machine is said to perform at twice the speed of a 33 MHz 80386-based microcomputer and three times the speed of a 25 MHz 386. Unlike its competitors, IBM did not design its 486 machine specifically to act as a server.

3 new I.B.M. models due on Monday

Article Abstract:

IBM plans the introduction of three new models of the company's PS/1 home computer. The introduction is scheduled for Monday, Oct 7, 1991. The new computers all are built around Intel's 80386SX microprocessor. They will be faster and more powerful than previous PS/1s, which used Intel's 80286 chips. Two of the new PS/1s will be available as of the announcement, one without expansion slots, and the other with two. Both will come with 2Mbytes of RAM and 40 Mbyte hard drives. A more powerful machine is scheduled for availability in 1992. It will run IBM's OS/2 operating system. The company also plans to unveil new models of its PS/2 line in late October 1991.
