Question: Lambda 8300 and Dragon 32/64, are electronic devices?

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: Komputer 2086: The Unipolbrit Komputer 2086 was a Polish version of the home computer Timex Sinclair 2068, produced by a joint venture of the Polish Unimor and Timex Computer of Portugal. The machine wasn't 100% ZX Spectrum-compatible (like all other Timex Sinclair versions) and a "Spectrum Emulation" cartridge was available (usually bundled).
Document 3: 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.
Document 4: Dragon Data: Dragon Data was a Welsh producer of home computers during the early 1980s. These computers, the Dragon 32 and Dragon 64, strongly resembled the Tandy TRS-80 Color Computer ("CoCo")—both followed a standard Motorola datasheet configuration for the three key components (CPU, SAM and VDG). The machines came in both 32KB and (later) 64KB versions.
Document 5: 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 6: Sea Dragon (video game): Sea Dragon is a side-scrolling game for the TRS-80 computer, written by Wayne Westmoreland and Terry Gilman, and released in 1982 by Adventure International. It was one of the most popular games for the TRS-80. Its success on the TRS-80 led to ports to the Apple II, Atari 8-bit family, Commodore 64, IBM PC, and the TRS-80 Color Computer.
Document 7: 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 8: Power 3000: Power 3000 was a Sinclair ZX81 clone from Creon Enterprises. Identical with Lambda 8300 and PC 8300.
Document 9: 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 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: 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 12: Timex Sinclair 2048: The Timex Sinclair 2048 although never produced, was to be an improved version of the Sinclair ZX Spectrum computer. It was not released by Timex Corporation because of TS1500 failure. According to an early Timex Sinclair 2000 computer flyer, it would be a cut-down TS2068 with 48 KB of RAM and advertised as a 48 KB memory machine (The TS2068 might have been called the 2072 because of the add of 24 KB ROM + 48 KB RAM = 72KB).
Document 13: 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 14: PC 8300: PC 8300 was a Sinclair ZX81 clone from China with rubber keys, joystick port and monitor port. Identical to Lambda 8300 and Power 3000.
Document 15: TRS-80 Color Computer: The Radio Shack TRS-80 Color Computer (also marketed as the Tandy Color Computer and affectionately nicknamed CoCo) is a line of home computers based on the Motorola 6809 processor. The Color Computer was launched in 1980, and lasted through three generations of hardware until being discontinued in 1991.
