− | The '''μCOM-42''' | + | The '''μCOM-42''' was [[microprocessor family|family]] of {{arch|4}} [[microcontroller]]s, part of the {{nec|μCOM-4|μCOM-4 extended family}}, specifically marketed for electronic cash registers (ECRs), Point of Sale (POS), and electronic scale applications. These chips were specifically designed for controlling 8x4 keyboards, 8-digit displays, and various ECR-type printers. The μCOM-42 had a separate, modified instruction set, compared with the rest of the {{nec|μCOM-4}} families. |
