A processor made by Western Digital, consisting of at least four separate integrated circuits, including the control circuitry unit, the ALU, two or four ROM chips with microcode, and timing circuitry. The ALU chip contained twenty-six 8-bit registers and an 8-bit ALU, while the control unit supervised the moving of data, memory access, and other control functions. The ROM allowed the chip to function as either an 8- or 16-bit chip, with clever use of the 8-bit ALU. Further, microcode allowed the addition of floating-point routines (40 + 8 bit format), simplifying programming (and possibly producing a floating-point coprocessor). Two standard microcode ROMs were available. This flexibility was one reason it was also used to implement the DEC LSI-11 processor as well as the WD {Pascal Microengine}. (1994-11-18)

The MCP-1600 is a multi-chip microprocessor made by Western Digital in the late 1970s through the early 1980s. Used in the Pascal MicroEngine, the WD16 processor in the Alpha Microsystems AM-100, and the DEC LSI-11 microcomputer, a cost-reduced and compact implementation of the DEC PDP-11.

Fashion in the period 1600–1650 in Western European clothing is characterized by the disappearance of the ruff in favour of broad lace or linen collars. Waistlines rose through the period for both men and women.
