TI-99/2, [42] a 4K RAM, 32K ROM computer with no color, sound, or joystick port and a Mylar keyboard. TI designed the computer in four and a half months to sell for under $100 and compete with the Sinclair ZX81 and Timex Sinclair 1000. Based on the TMS9995 CPU running at 10.7 MHz and with a built-in RF modulator, performance greatly increased ...
Decade counter – modulus ten counter (counts through ten states). Up/down counter – counts up and down, as directed by a control input, or by the use of separate "up" and "down" clocks. Ring counter – formed by a "circular" shift register. Johnson counter – a twisted ring counter. Gray-code counter – outputs a sequence of Gray codes.
With this improvement, more complex and reliable CPUs were built onto one or several printed circuit boards containing discrete (individual) components. In 1964, IBM introduced its IBM System/360 computer architecture that was used in a series of computers capable of running the same programs with different speeds and performances. [36]
These "in-flight" instructions can retire at any time, depending on memory access, hits in cache, stalls in the pipeline and many other factors. This can cause performance counter events to be attributed to the wrong instructions, making precise performance analysis difficult or impossible. AMD introduced methods to mitigate some of these ...
The IBM 5100 Portable Computer is one of the first portable computers, [1] ... clock counter, etc., using hexadecimal codes equivalent to assembly language. This ...
A kit-built Altair 8800 computer with the popular Model 33 ASR (Automatic Send and Receive) Teletype as terminal. The typical MITS product had a generic name like the "Model 1440 Calculator" or the "Model 1600 Digital Voltmeter". Ed Roberts was busy finishing the design and left the naming of the computer to the editors of Popular Electronics.

The counter machine models go by a number of different names that may help to distinguish them by their peculiarities. In the following the instruction "JZDEC ( r )" is a compound instruction that tests to see if a register r is empty; if so then jump to instruction I z, else if not then DECrement the contents of r:
