The chips contained 4-bit [[ALU]] performing [[BCD]] arithmetic. 512 to 2,048 Words (10-bit ea) of program [[ROM]]. Additional 128 Words (10-bit ea) of pattern ROM. 32 to 160 digits (4-bit ea) of data [[RAM]]. Chips also contained Event/Timer-Counter and 22-44 I/O lines. Output was aimed for driving dot matrix Liquid Crystal displays. The HMCS40 was used in a very large array of games, toys, controllers, and office equipment, specifically many devices with VFDs. | The chips contained 4-bit [[ALU]] performing [[BCD]] arithmetic. 512 to 2,048 Words (10-bit ea) of program [[ROM]].
