Vadem Inc, San Jose is offering a chip set that enables the highly-integrated – lots of support circuits with the CPU – Intel 80C186 microprocessor to be used as the basis of cheap micros compatible with IBM’s – simultaneously discontinued – PS/2 Model 30, or long-abandoned XT: the Vadem VG-501 and VG-502, and a 16MHz 80C186, provide the first high-performance chip-set solution for lower-priced MS-DOS systems – and the set, developed under an agreement with Intel’s Microcomputer/ASIC division in Chandler, Arizona, certainly is cheap – the VG 501/502 set costs just $31 in 1,000-up quantities, comes in two 84-pin PLCC packages, and samples in November with volume inked in for first quarter 1989.
