The is a 4-bit slice Program Control Unit (PCU) produced by Advanced Micro Devices (AMD) as part of their 2900 series of microprogrammable bipolar devices. It is designed to handle program control functions, such as address sequencing and subroutine management, in high-performance microprogrammed systems.
