Chip Hall of Fame: Motorola MC68000 Microprocessor

was late to the 16-bit microprocessor party, so it decided to arrive in style. The hybrid 16-bit/32-bit MC68000 packed in 68,000 transistors, more than double the number of Intel’s 8086. Internally it was a 32-⁠bit processor, but a 32-bit address and/or data bus would have made it prohibitively expensive, so the 68000 used 24-bit address and 16-bit data lines. The 68000 seems to have been the last major processor designed using pencil and paper. “I circulated reduced-size copies of flowcharts, execution-unit resources, decoders, and control logic to other project members,” says Nick Tredennick , who designed the 68000’s logic. The copies were small and difficult to read, and his bleary-eyed colleagues eventually found a way to make that clear. “One day I came into my office to find a credit-card-size copy of the flowcharts sitting on my desk,” Tredennick recalls. The 68000...
