Western Digital Corp, Irvine, California has new chip sets for personal computer builders wanting to build AT-alikes and Micro Channel-compatible machines around around Intel’s new low-cost 80386SX 16-bit bus microprocessor. The FE3600 core logic chip set is designed to enable designers to get to market quickly with AT-alikes: claimed to be 100% register-level hardware- and software-compatible with the AT, it comprises four surface mountable 1.25 micron CMOS devices and compared with rival products is claimed to offer higher levels of integration, increased reliability, and reduced board space requirements, leaving room for optional integration of additional functionality. The set costs $74.50 when you buy 10,000 or more of the things. And for those who want to build a Micro Channel machine around the 80386SX – IBM does not yet have such a thing in the PS/2 line – the FE5400SX core logic chip set consists of four surface-mountable, 132-pin JEDEC plastic quad flat pack CMOS devices, and it offers the same benefits as the FE3600. The chip set costs $185 when you order 100 or more.
