The PDP-14 was designed to process Boolean equations, usually expressed as “ladder diagrams” and as such had a programmable read-only program memory. Programs were developed using a PDP-8 then tested using a direct connection to the PDP-14. The PDP-14 was put into a check out mode where instructions were provided by the PDP-8.
The D-500 Amino Acid Analyzer was designed and built by Durrum Instruments in the late 1960s. It was used by many prestigious universities and research facilities to test for presence and quantity of amino acids in biological samples.
PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
It is the successor to PAL-11 (Program Assembler Loader), an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 is supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (called "as"), structurally similar to MACRO-11, but with different syntax and fewer features.
The PDP-7 was introduced in December 1964, and about 120 were eventually produced. [25] An upgrade to the Flip Chip led to the R series, which in turn led to the PDP-7A in 1965. [26] The PDP-7 is most famous as the machine for which the Unix operating system was originally written. [27] Unix ran only on DEC systems until the Interdata 8/32. [28]
In calibrating ECUs, control behavior is modified for different vehicle models or variants. This is not done by making changes to the program code, but instead by changing the ECU's parameterization. This involves the use of measurement and calibration systems such as CANape in the laboratory, on test benches or in vehicles during test trials.
The Ford EEC or Electronic Engine Control is a series of ECU (or Engine Control Unit) that was designed and built by Ford Motor Company. The first system, EEC I, used processors and components developed by Toshiba in 1973. It began production in 1974, and went into mass production in 1975. It subsequently went through several model iterations.
An asynchronous control bus used to access memory-mapped I/O registers in the individual storage devices, [1]: 8.0 and; A high-speed, synchronous data bus that is used to carry the actual data transfers between the storage devices and the host bus adapter. [1]: 8.0 The data bus is 18 bits wide plus parity. [1]: 34.0
