Question: Which was a computer that also played video games, APF Imagination Machine or Grundy NewBrain?

full_context: Document 1: Entertainment Computer System: The Entertainment Computer System was an add-on peripheral for the Intellivision. It was Mattel Electronics' second attempt at creating a peripheral to upgrade the Intellivision into a home computer, rushed into production to appease the Federal Trade Commission after they began fining Mattel for false advertising following consumer complaints about the repeated delays in releasing the originally planned Intellivision Keyboard Component add-on. The Entertainment Computer System or ECS includes the Computer Module, Music Synthesizer, and additional hand controllers; each sold separately. Any Intellivision Master Component is compatible and a requirement to use the system.
Document 2: VTech CreatiVision: The Video Technology CreatiVision is a hybrid computer and home video game console introduced by VTech in 1981 and released in 1982. The hybrid unit was similar in concept to computers such as the APF Imagination Machine, the older VideoBrain Family Computer, and to a lesser extent the Intellivision game console and Coleco Adam computer, all of which anticipated the trend of video game consoles becoming more like low-end computers.
Document 3: TRS-80 MC-10: The TRS-80 MC-10 microcomputer is a lesser-known member of the TRS-80 line of home computers, produced by Tandy Corporation in the early 1980s and sold through their RadioShack chain of electronics stores. It was apparently designed as a low-cost alternative to Tandy's own TRS-80 Color Computer to compete with entry-level machines that had previously dominated the market, such as the Commodore VIC-20 and Sinclair ZX81.
Document 4: APF Imagination Machine: The APF Imagination Machine is a combination home video game console and computer system released by APF Electronics Inc. in late 1979. It was composed of two separate components, the APF-M1000 game system, and an add on docking bay with full sized typewriter keyboard and tape drive. The APF-M1000 was built specifically to compete with the Atari 2600. The Imagination Machine has the distinction of being one of, if not the first, affordable home PCs to connect to the television, and is still one of the most expandable consoles ever marketed. The full APF Imagination Machine, including the APF-M1000 console and the IM-1 computer component originally sold for around $700.
Document 5: APF-MP1000: The APF Microcomputer System is a second generation 8-bit cartridge-based home video game console released in 1978 by APF Electronics Inc with six cartridges. The console is often referred to M-1000 or MP-1000, which are the two model numbers of the console. The controllers are non-detachable joysticks which also have numeric keypads. The APF-MP1000 comes built-in with the game "Rocket Patrol". The APF-MP1000 is a part of the APF Imagination Machine.
Document 6: Acorn Electron: The Acorn Electron is a budget version of the BBC Micro educational/home computer made by Acorn Computers Ltd. It has 32 kilobytes of RAM, and its ROM includes BBC BASIC v2 along with its operating system.
Document 7: Timex Sinclair 1000: The Timex Sinclair 1000 (TS1000) was the first computer produced by Timex Sinclair, a joint venture between Timex Corporation and Sinclair Research. It was launched in July 1982, with a US sales price of US$99.95, making it the cheapest home computer to date; it was advertised as "the first computer under $100". The computer was aimed at regular home users. Unlike earlier computers aimed at home users, the TS1000 was not a kit which had to be soldered and assembled. As purchased, the TS1000 was fully assembled and ready to be plugged into the users' home TV (which served as a video monitor). The TS1000 was a slightly-modified version of the Sinclair ZX81 with an NTSC RF modulator, designed for use with North American TVs, instead of the UK PAL RF modulator which was used for units sold in Portugal. The TS1000 doubled the onboard RAM from 1 KB to 2 KB. The TS1000's casing had slightly more internal shielding but remained the same as Sinclair's, including the membrane keyboard. It had black-and-white graphics and no sound. It was followed by an improved version, the Timex Sinclair 1500 which had substantially more RAM (16 KB) and a lower price (US$80). However, the TS1500 did not achieve market success, given that the marketplace was by this time dominated by Commodore, RadioShack, Atari and Apple.
Document 8: Acorn Atom: The Acorn Atom is a home computer made by Acorn Computers Ltd from 1980 to 1982, when it was replaced by the BBC Micro (originally "Proton").
Document 9: Interact Home Computer: The Interact Home Computer is a rare, very early (1978) American home computer made by "Interact Electronics Inc" of Ann Arbor, Michigan. It sold under the name "interact Model One home computer". The original Ineract Model One computer was designed by Rick Barnich and Tim Anderson at 204 E. Washington in Ann Arbor, then moving to an office in Georgetown Mall on Packard St in Ann Arbor. Interact Electronics Inc was a privately held company that was funded by Hongiman, Miller, Swartz and Cohn...a lawyer firm out of Detroit. The President/Founder of Interact Electronics Inc was Ken Lochner, who was one of the original developers of the BASIC language based out of Dartmouth college. Ken had started Interact Electronics Inc after a successful startup known as ADP Cyphernetics, the original computer time share company in Ann Arbor, now known as ADP Network Services. Only a few thousand Interacts were sold before the company went bankrupt. Most were sold by the liquidator "Protecto Enterprizes" of Barrington, Illinois through mail order sales. The Interact Model One Home Computer debuted at the Consumer Electronics Show in Chicago in June 1978 at a price of $499. The majority of sales were thru Mail Order houses and you could buy it off the shelf at Highland Appliance in the Detroit, MI area and Newman Computer Exchange in Ann Arbor. Probably the most successful application available for the Interace was a program called "Message Center". With it, a store could type in whatever message they wanted to appear scrolling on a TV screen...like Advertisements, or welcoming messages to guests in an office. Although it was mostly a Game machine at the time with games such as Showdown, BlackJack and Chess, there was also BASIC programming where users could create their own programs in the BASIC computer language. Customers began hooking up Interact to control everything from lights in their house, to a Chevrolet Corvette!
Document 10: Acorn Computers: Acorn Computers Ltd. was a British computer company established in Cambridge, England, in 1978. The company produced a number of computers which were especially popular in the UK, including the Acorn Electron and the Acorn Archimedes. Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s. It is more known for its BBC Micro model B computer than for its other products.

Document 12: Fairchild Channel F: The Fairchild Channel F is a home video game console released by Fairchild Semiconductor in November 1976 across North America at the retail price of $169.95. It was also released in Japan in October the following year. It has the distinction of being the first programmable ROM cartridge–based video game console, and the first console to use a microprocessor. It was launched as the Video Entertainment System, or VES, but when Atari released its VCS the next year, Fairchild renamed its machine. By 1977, the Fairchild Channel F had sold 250,000 units, trailing behind sales of the VCS.
Document 13: TRS-80: The TRS-80 Micro Computer System (TRS-80; later known as the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of "Tandy/Radio Shack, Z-80 microprocessor". It was one of the earliest mass-produced and mass-marketed retail personal computers.
Document 14: ZX81: The ZX81 is a home computer produced by Sinclair Research and manufactured in Scotland by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be a low-cost introduction to home computing for the general public. It was hugely successful, and more than 1.5 million units were sold before it was discontinued. The ZX81 found commercial success in many other countries, notably the United States, where it was initially sold as the ZX-81. Timex manufactured and distributed it under licence and enjoyed a substantial but brief boom in sales. Timex later produced its own versions of the ZX81 for the US market – the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorised clones of the ZX81 were produced in several countries.
Document 15: BBC Micro: The BBC Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by the Acorn Computer company for the "BBC Computer Literacy Project", operated by the British Broadcasting Corporation. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. An accompanying 1982 television series ""The Computer Programme"" featuring Chris Serle learning to use the machine was also broadcast on BBC 2.
