The Western Design Center (WDC), located in
MOS Technology 65xx based microprocessors, microcontrollers (µCs), and related support devices. WDC was founded in 1978 by a former MOS Technology employee and coholder of the MOS Technology 6502 patent, Bill Mensch.[1]
Beyond discrete devices, WDC offers device designs in the form of
in-circuit emulators
for their processors.
