The '''GI SBA''' ('''General Instrument Microelectronics Sequential Boolean Analyzer''') is a [[1-bit architecture]] microprocessor developed by [[General Instrument|General Instrument's Microelectronics]] division. The chip featured 24 basic instructions, 1023 words of ROM, 16-level stack, and storage. The [[GI SBA-1]] is an identical chip without the ROM; ROM data lines were brought out instead to allow external storage.
