Question: Were both Memotech MTX and TEC-1 single-board kit computers?

full_context: Document 1: Atari 8-bit family: The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 and manufactured until 1992. All of the machines in the family are technically similar and differ primarily in packaging. They are based on the MOS Technology 6502 CPU running at 1.79 MHz, and were the first home computers designed with custom co-processor chips. This architecture enabled graphics and sound capabilities that were more advanced than contemporary machines like the Apple II or Commodore PET, and gaming on the platform was a major draw. "Star Raiders" is considered the platform's killer app.
Document 2: 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 3: 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 4: Dragon MSX: The Dragon MSX MSX 1 home computer was designed by Radofin (the creators of the Mattel Aquarius) for Dragon Data, which were well known for their Dragon 64 home computer, a clone of the TRS-80 Color Computer.
Document 5: ZX81 character set: The ZX81 character set is the character encoding used by the Sinclair Research ZX81 family of microcomputers including the Timex Sinclair 1000 and Timex Sinclair 1500. The encoding uses one byte per character for 256 code points. It has no relationship with previously established ones like ASCII or EBCDIC, but it is related though not identical to the character set of the predecessor ZX80.
Document 6: Lambda 8300: The Lambda 8300 was a Sinclair ZX81 clone from Lambda Electronics Limited of Hong Kong. It was not an exact clone as it had a modified ZX81 ROM, but could be fitted with a ZX81 compatible ROM. It came with 2K RAM (expandable to 16 or 32 K), and a sound and joystick port. Specifically, it used a Z80A microprocessor at 3.25 MHz. It was identical to the DEF 3000, PC 2000, Marathon 32K, IQ 8300, PC 8300, Power 3000, Unisonic 8300, Futura 8300, Basic 2000 and Basic 3000.
Document 7: Elektor TV Games Computer: The Elektor TV Games Computer (TVGC) was a programmable computer system sold by Elektor in kit form from 1979. It used the Signetics 2650 CPU with the Signetics 2636 PVI for graphics and sound. These were the same chips as used in the Interton VC 4000 console family. A 2K monitor ROM written by Philips and a cassette interface were the most important differences between the TVGC and the Interton family. Many VC 4000 games were adapted versions of TV Games Computer games. It is possible to add cartridge slots to the TVGC to enable it to play console games, and the Hobby Module of the Acetronic console effectively transforms it into a basic TVGC.
Document 8: Mark-8: The Mark-8 is a microcomputer design from 1974, based on the Intel 8008 CPU (which was the world's first 8-bit microprocessor). The Mark-8 was designed by graduate student Jonathan Titus and announced as a 'loose kit' in the July 1974 issue of "Radio-Electronics" magazine.
Document 9: EDUC-8: The EDUC-8, pronounced "educate", was an early microcomputer kit published by Electronics Australia in a series of articles starting in August 1974 and continuing to August 1975. Electronics Australia initially believed that it was the first such kit, but later discovered that Radio-Electronics had just beaten it with their Mark-8 by one month. However, Electronics Australia staff believed that their TTL design was superior to the Mark-8, as it did not require the purchase of an expensive microprocessor chip.
Document 10: 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 11: 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 12: Dragon 32/64: The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.
Document 13: TEC-1: 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.
Document 14: Aster CT-80: The Aster CT-80, an early (1982) home/personal computer developed by the small Dutch company MCP (later renamed to Aster Computers), was sold in its first incarnation as a kit for hobbyists. Later it was sold ready to use. It consisted of several Eurocard PCB's with DIN 41612 connectors, and a backplane all based on a 19-inch rack configuration. It was the first commercially available Dutch personal/home computer. The Aster computer could use the software written for the popular Tandy TRS-80 computer while fixing many of the problems of that computer, but it could also run CP/M software, with a big amount of free memory Transient Program Area, (TPA) and a full 80×25 display, and it could be used as a Videotext terminal. Although the Aster was a clone of the TRS-80 Model I it was in fact more compatible with the TRS-80 Model III, and ran all the software of these systems including games. It also had a built in speaker which was compatible with such games software.
Document 15: Memotech MTX: 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.
