Series 8000 or ALPS (Advanced Logic Processor System) was a family of low-end 8-bit microprocessor chipset developed by General Instrument. Designed in the United Kingdom, this series saw most of its success in the European market. A minimum system could be built from just two chips and a single-phase clock, which was smaller than many of the other alternatives at the time. At the heart of the system is the LP 8000 microprocessor unit.


All part numbers are prefixed with LP (Logic Processor).

Part Description
LP 8000 8-bit MPU
LP 6000 Program Memory (PM)
LP 1000 Memory interface chip (MIC)
LP 1010 input/output buffer (IOB)
LP 1030 clock generator (CG)
