Bit slicingBit slicing is a technique for constructing a processor from modules of processors of smaller bit width, for the purpose of increasing the word length; in theory to make an arbitrary n-bit central processing unit (CPU). Each of these component modules processes one bit field or "slice" of an operand. The grouped processing components would then have the capability to process the chosen full word-length of a given software design. Bit slicing more or less died out due to the advent of the microprocessor.
IntersilIntersil Corporation est un fondeur spécialisé dans la conception et la fabrication de semi-conducteurs analogiques et est basé à Milpitas, en Californie. Intersil a été créée par un des cofondateurs de Fairchild, Jean Hoerni, en 1967. Au début, Intersil est spécialise dans les circuits CMOS pour les montres Seiko. Son générateur de signaux ICL8038 était une combinaison de diodes Schottky. Il permettait de produire des sinusoïdes, des signaux en créneaux ou en dents de scies.
Résistance-transistorvignette|Une porte logique NON-OU utilisée dans l'Apollo Guidance Computer. Résistance-transistor ou RTL est une famille de circuits logiques utilisée en électronique. Appelée aussi resistor-transistor logic, c'est la famille la plus simple de portes logiques utilisant des transistors bipolaires. C'est la plus dépouillée des familles de circuits logiques, utilisées jusqu'au tout début des années 1970. Au contraire des portes à diodes, elles peuvent être mises en cascade indéfiniment, afin de produire des fonctions logiques plus complexes.
Porte logique diode-transistorthumb|Diode-transistor Logic (DTL) La Diode-Transistor logic ou DTL est une famille de circuits logiques utilisée en électronique numérique. Ils ont succédé à la famille logique à transistors bipolaires appelée "résistance-transistor" ou RTL (resistor-transistor logic). Pour diminuer le temps de retard, les résistances utilisées par les portes RTL furent remplacées par des diodes, ce qui donna naissance aux portes logiques diode-transistor ou DTL (diode-transistor logic).

Circuits statiques et dynamiquesIn integrated circuit design, dynamic logic (or sometimes clocked logic) is a design methodology in combinational logic circuits, particularly those implemented in metal–oxide–semiconductor (MOS) technology. It is distinguished from the so-called static logic by exploiting temporary storage of information in stray and gate capacitances. It was popular in the 1970s and has seen a recent resurgence in the design of high-speed digital electronics, particularly central processing units (CPUs).
Through-hole technologyIn electronics, through-hole technology (also spelled "thru-hole") is a manufacturing scheme in which leads on the components are inserted through holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side, either by manual assembly (hand placement) or by the use of automated insertion mount machines. Through-hole technology almost completely replaced earlier electronics assembly techniques such as point-to-point construction.
Glue logicIn electronics, glue logic is the custom logic circuitry used to interface a number of off-the-shelf integrated circuits. This is often achieved using common, inexpensive 7400- or 4000-series components. In more complex cases, a programmable logic device like a CPLD or FPGA might be used. The falling price of programmable logic devices, combined with their reduced size and power consumption compared to discrete components, is making them common even for simple systems.
DatapointDatapoint Corporation, originally known as Computer Terminal Corporation (CTC), was a computer company based in San Antonio, Texas, United States. Founded in July 1968 by Phil Ray and Gus Roche, its first products were, as the company's initial name suggests, computer terminals intended to replace Teletype machines connected to time sharing systems. From the mid-1960s, engineers (John) Phil Ray and Austin O. "Gus" Roche were working for General Dynamics Dynatronic Division in Florida, as part of a computing contract team for NASA to enable President John F.
