MCP-1600
A processor made by Western Digital, consisting of at least four separate integrated cIRcuits, including the control c IRcuitry unit, the ALU, two or four ROM chips with microcode, and timing c IRcuitry. 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}.
