- Am2900 is a family of integrated circuits (ICs) created in 1975 by Advanced Micro Devices (AMD). They were constructed with bipolar devices, in a bit-slice topology, and were designed to be used as modular components each representing a different aspect of a computer control unit (CCU). By using the bit slicing technique, the Am2900 family was able to implement a CCU with data, addresses, and instructions to be any multiple of four bits by multiplying the number of ICs. This requires more ICs to implement than what could be done on a single CPU IC, but at the time, the TTL Am2900 chips ran at 20–40 MHz, which was much faster than the 2–3 MHz CMOS/NMOS microprocessors of the era such as the Intel 8085. 8085 emulators were implemented around two Am2900 chips which ran 5 to 10 times faster than the 8085-based designs they replaced.

Western State Hospital is a psychiatric hospital located at 9601 Steilacoom Boulevard SW in Lakewood, Washington. Administered by the Washington Department of Social and Health Services (DSHS), it is a large facility with 806 beds, and Washington’s second-oldest state-owned enterprise (after the University of Washington).
