Question: KIM-1 was produced by a semiconductor design and fabrication company that is based in what city in Pennsylvania?

Context paragraphs:
Technology CAD: Technology CAD (or Technology Computer Aided Design, or TCAD) is a branch of electronic design automation that models semiconductor fabrication and semiconductor device operation.  The modeling of the fabrication is termed Process TCAD, while the modeling of the device operation is termed Device TCAD.  Included are the modelling of process steps (such as diffusion and ion implantation), and modelling of the behavior of the electrical devices based on fundamental physics, such as the doping profiles of the devices.  TCAD may also include the creation of "compact models" (such as the well known SPICE transistor models), which try to capture the electrical behavior of such devices but do not generally derive them from the underlying physics.  (However, the SPICE simulator itself is usually considered as part of ECAD rather than TCAD.)

PortalPlayer: PortalPlayer, founded in 1999, was a fabless semiconductor company that supplied system-on-a-chip semiconductors, firmware and software for personal media players.  The company handled semiconductor design and firmware development, while subcontracting the actual semiconductor manufacturing to merchant foundries.

Ingenic Semiconductor: Ingenic Semiconductor is a Chinese fabless semiconductor company based in Beijing, China founded in 2005.  They purchased licenses for the MIPS architecture instruction sets in 2009 and design CPU-microarchitectures based on them.  They also design system on a chip products including their CPUs and licensed semiconductor intellectual property blocks from third parties, such as Vivante Corporation, commission the fabrication of integrated circuits at semiconductor fabrication plants and sell them.

Holtek: Holtek Semiconductor is a Taiwan-based semiconductor design centre and provider.  Along with its headquarters and design operations based in the Hsinchu Science Park in Taiwan, Holtek operates worldwide with a wide range of global agents.  Holtek's design focus is in both 32-bit and 8-bit microcontroller development with the company having around 650 employees.  Holtek also designs and provides peripheral semiconductor products such as remote control, telecommunication, power management, computer peripheral, and memory devices.  Holtek's device application area is concentrated in the consumer product field such as household appliances, computer peripheral products, remote controllers, leisure products, medical equipment as well as industrial controllers.  Holtek microcontrollers are in home appliances including brands such as Philips, Siemens, Märklin and Japanese brands such as Futaba and Sony.

Cypress Semiconductor: Cypress Semiconductor Corporation is an American semiconductor design and manufacturing company.  It offers NOR flash memories, F-RAM and SRAM Traveo microcontrollers, the industry’s only PSoC programmable system-on-chip solutions, analog and PMIC Power Management ICs, CapSense capacitive touch-sensing controllers, Wireless BLE Bluetooth Low-Energy and USB connectivity solutions.

SSMC: Systems on Silicon Manufacturing Co.  Pte. Ltd. (more commonly known as SSMC) is a Singaporean semiconductor fabrication company located in Pasir Ris Wafer Fab Park.  It was incorporated in 1999 and is a joint venture between NXP Semiconductors and TSMC.  Founded by NXP Semiconductors and EDB Investments, the plant was completed in 2000.

Midwest Steel &amp; Iron Works: Midwest Steel & Iron Works was a metal fabrication company based in Denver, Colorado.  Founded in 1893, the company was known for a time as the Jackson-Richter Iron Works.  The company was one of the "oldest and largest metal fabricators" in Denver.  The company built both structural and ornamental components for structures throughout Colorado, Wyoming and New Mexico.  The company's headquarters on Larimer Street in Denver includes an Art Deco office building and consists of a four-building complex that is itself considered a historic industrial site.  The complex served as the company's headquarters from 1923 to 1983.

Murray-Latta: The Murray-Latta Machine Company is a British Columbian machine manufacturing and steel fabrication company.  In the 1960s and 1970s, they built a number of chairlifts, mainly in British Columbia.  Although they no longer design or fabricate chairlifts, they still provide parts and act as contractors for constructing new lifts designed by other manufacturers.

MOS Technology: MOS Technology, Inc. ("MOS" being short for Metal Oxide Semiconductor), also known as CSG (Commodore Semiconductor Group), was a semiconductor design and fabrication company based in Norristown, Pennsylvania, in the United States.  It is most famous for its 6502 microprocessor and various designs for Commodore International's range of home computers.

KIM-1: The KIM-1, short for "Keyboard Input Monitor", was a small 6502-based single-board computer developed and produced by MOS Technology, Inc. and launched in 1976.  It was very successful in that period, due to its low price (following from the inexpensive 6502) and easy-access expandability.
