Chip giant Intel has discontinued manufacture of the Celeron 300a desktop processor, the Pentium II 333MHz part and Pentium mobile with MMX 300, 266 and 266MHz low power chips. It explained the move by saying the company is experiencing a rapid market conversion to higher performance chips in both those segments. Intel is notifying all of its customers, and they will have four months up until the 25th of June this year to place final orders for the mobile Pentium parts. Customers will have twelve months to place orders for the 300a desktop part, and eighteen months for the PII/333 chip. ®
