The '''National MAPS''' ('''''M'''icroprogrammable '''A'''rithmetic '''P'''rocessor '''S'''ystem'') or '''National MM570X''' was a bit-serial [[microcontroller]] system made of 5 discrete chips designed by [[National Semiconductor]]. The system can be programmed to operate in binary or BCD up to a 76 bit one cycle data word.The chipset was marketed as a general purpose serieal data microcomputer system. The chipset was introduced in late 1971{{date off}} but was quickly replaced within a year.

The National MAPS (Microprogrammable Arithmetic Processor System) or National MM570x was a family of multi-chip bit-serial microcontrollers designed by National Semiconductor. The system was made of 5 discrete chips designed to operate on variable-sized words. The system can be programmed to operate in binary or BCD up to a 76 bit one cycle data word. The chipset was marketed as a general purpose serial data microcomputer system. The chipset was introduced in late 1971 but was quickly replaced within a few short years.
