Level 9 was a British developer of computer software, active between 1981 and 1991.
 Founded by Mike, Nicholas and Pete Austin, the company produced software for the BBC Micro, Nascom, ZX Spectrum, Commodore 64, Oric, Atari, Lynx 48k, RML 380Z, Amstrad CPC, MSX, Amiga, Apple II, Memotech MTX, and Enterprise platforms and is best known for its successful text adventure games until a general decline in the text adventure market forced their closure in June 1991.
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer.
 Single-board computers were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers.
 Many types of home computers or portable computers integrate all their functions onto a single printed circuit board.
Creator is a family of single-board computers developed by Imagination Technologies to promote educational research and software development based on the MIPS architecture.
 The first board in the platform, the Creator Ci20, was released in August 2014.
 A second development kit called Creator Ci40 was introduced through a Kickstarter campaign in November 2015.

Felix in the Factory is a platform game for home computers published by Micro Power (a.k.a. Program Power).
 The game was first released in 1982 for the BBC Micro.
 It was ported to the Acorn Electron (1983), Commodore 64 (1984) and Memotech MTX (1984).
 It is the first in a trilogy of Micro Power games featuring the factory worker Felix and was followed by "Felix and the Fruit Monsters" (a Pac-Man style overhead maze game) and another factory-based platformer, "Felix meets the Evil Weevils".
The TEC-1 is a single-board kit computer first produced by the Australian hobbyist electronics magazine Talking Electronics in the early 1980s.
 It was based on the Zilog Z80 CPU, had 2K of RAM and 2K of ROM in a default configuration.
 Later versions used a 4k ROM with two different versions of the monitor software selectable via a switch.
 This allowed the early software presented in the magazine to be used with the later version of the TEC-1.
Each time Intel launched a new microprocessor, they simultaneously provided a System Development Kit (SDK) allowing engineers, university students, and others to familiarise themselves with the new processor's concepts and features.
 The SDK single-board computers allowed the user to enter object code from a keyboard or upload it through a communication port, and then test run the code.
 The SDK boards provided a system monitor ROM to operate the keyboard and other interfaces.
 Kits varied in their specific features but generally offered optional memory and interface configurations, a serial terminal link, audio cassette storage, EPROM program memory.
 Intel's Intellec development system could download code to the SDK boards.
The Memotech MTX500, MTX512 and RS128 were a series of Zilog Z80A processor-based home computers released by Memotech in 1983 and 1984.
 They were technically similar to MSX computers, but were not compatible.
Pine64 is a family of single-board computers and the name of the company that produces them.
 Their first single-board computer, the Pine A64, was designed to compete with the Raspberry Pi in both power and price.
 Its name descends from the constant variables pi and Euler's constant.
 The A64 was first funded through a Kickstarter crowdfunding drive in December 2015, where the company raised over $1.4 million.

Question: Were both Memotech MTX and TEC-1 single-board kit computers?
Answer: no
