The DISCiPLE was a floppy disk interface for the Sinclair ZX Spectrum home computer.
 Designed by Miles Gordon Technology, it was marketed by Rockfort Products and launched in 1986.
The SAM Coupé (pronounced /sæm ku:peɪ/ from its original British English branding) is an 8-bit British home computer that was first released in late 1989.
 It is commonly considered a clone of the Sinclair ZX Spectrum computer, since it features a compatible screen mode and emulated compatibility, and it was marketed as a logical upgrade from the Spectrum.
 It was originally manufactured by Miles Gordon Technology (MGT), based in Swansea in the United Kingdom.
This is a list of games for the SAM Coupé.
 The SAM Coupé is a British 8-bit home computer manufactured by Miles Gordon Technology (MGT) and released in 1989.
The +D (or Plus D) was a floppy disk and printer interface for the Sinclair ZX Spectrum home computer, developed as a successor to Miles Gordon Technology's earlier product, the DISCiPLE.
 It was designed to be smaller, cheaper, simpler and thus more reliable.
Miles Gordon Technology, known as MGT, was a small British company, initially specialising in high-quality add-ons for the Sinclair ZX Spectrum home computer.
 It was founded in June 1986 in Cambridge, England by Alan Miles and Bruce Gordon, former employees of Sinclair Research, after Sinclair sold the rights for the Spectrum to Amstrad.
 They moved to Swansea, Wales, in May 1989, became a public company in July 1989 and went into receivership in June 1990.
Digital Light Processing (DLP) is a display device based on optical micro-electro-mechanical technology that uses a digital micromirror device.
 It was originally developed in 1987 by Larry Hornbeck of Texas Instruments.
 While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997.
 Digital Projection and Texas Instruments were both awarded Emmy Awards in 1998 for the DLP projector technology.
 DLP is used in a variety of display applications from traditional static displays to interactive displays and also non-traditional embedded applications including medical, security, and industrial uses.
Texas Instruments Inc. (TI) is an American technology company that designs and manufactures semiconductors, which it sells to electronics designers and manufacturers globally.
 Headquartered in Dallas, Texas, United States, TI is one of the top ten semiconductor companies worldwide, based on sales volume.
 Texas Instruments's focus is on developing analog chips and embedded processors, which accounts for more than 85% of their revenue.
 TI also produces TI digital light processing (DLP) technology and education technology products including calculators, microcontrollers and multi-core processors. To date, TI has more than 43,000 patents worldwide.
Datel (previously Datel Electronics) is a UK-based electronics and game console peripherals manufacturer.
 The company is best known for producing a wide range of hardware and peripherals for home computers in the 1980s, for example replacement keyboards for the ZX Spectrum, the PlusD disk interface (originally designed and sold by Miles Gordon Technology) and the Action Replay series of video game cheating devices.
Bernard A Yurash (February 17, 1921 – January 25, 2007) was a significant contributor to the creation of the first commercially viable CMOS integrated circuits by finding the sources of mobile sodium ions coming from the manufacturing process.
 Today, virtually all digital electronics use CMOS circuitry.
 Bernard worked at Fairchild Semiconductor in Silicon Valley from 1958 ( he was employee number 158 ), through the buyouts of the company by Schlumberger and National Semiconductor, and finally retiring in 1990.
 In the 1960s Fairchild Semiconductor, a division of Fairchild Camera and Instrument Corp., and Texas Instruments, revolutionized electronics by employing the first integrated circuit technology.
 Fairchild's Robert Noyce filed for this patent using deposited (printed) metal lines and Jean Hoerni's Planar Process ( patent also filed by Jack Kilby of Texas Instruments but with using bonding wires ).
 At the time virtually all the devices were of the bipolar type which were used to construct RTL and DTL type circuits ( Resistor-Transistor-Logic, Diode-Transistor-Logic), which unfortunately drew more power than was desired, and eventually lost ground to Texas Instruments' TTL (Transistor-Transistor-logic).
 The next great technological leap in computer chips would be CMOS transistors, which promised significantly lower power and greater circuit density than the Bipolar circuitry.
 Although Frank Wanlass first filed for the CMOS patent in 1963, Fairchild could not produce the devices for commercial output for many years because of the mystery of the mobile ions degrading their performance.
 Much research time and money was expended in 1967 and 1968 at Fairchild on trying to manufacture the highly promising technology, the MOS SGT ( Metal Oxide Semiconductor Silicon Gate Technology ) circuits utilizing the field effect from the "gate" on the conducting "channel" from source to drain.
The TI-Nspire product line is a series of graphing calculators developed by Texas Instruments.
 This line currently includes the "TI-Nspire", "TI-Nspire CAS", "TI-Nspire CX" and "TI-Nspire CX CAS".
 There are also models aimed for the Chinese market, named the "TI-Nspire CM-C", "TI-Nspire CX-C", "TI-Nspire CM-C CAS", "TI-Nspire CX-C CAS".
 There is also software available for Windows and Mac OS X that act in similar ways to the calculators and allow the user to create compatible files.
 This software either requires a license or can only be used for a limited time.
 However, Texas Instruments also provides separate software that can be used for an unlimited time without a license but only allows file transfers and not emulation of the calculator.
 In 2010, Texas Instruments updated the calculators to the Touchpad versions which come with the Nspire or Nspire CAS computer software and support optional rechargeable batteries.
 In 2011, TI announced two new models of the TI-Nspire series: Nspire CX and Nspire CX CAS.
 The main new features are the color screen, rechargeable battery and thinner design.

Question: Do Texas Instruments Inc. and Miles Gordon Technology create the same products?
