The Tandy 1000 was the first in a series of IBM PC compatible home computers produced by the Tandy Corporation, sold through its Radio Shack and Radio Shack Computer Center stores. Introduced in 1984, the Tandy 1000 line was designed to offer affordable yet capable systems for home computing and education. Tandy-specific features, such as enhanced graphics, sound, and a built-in joystick port, made the computers particularly attractive for home use.
MSX is a standardized home computer architecture, announced by ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, the director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines. The first MSX computer sold to the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official release date.
The Enhanced Graphics Adapter (EGA) is an IBM PC graphics adapter and de facto computer display standard from 1984 that superseded the CGA standard introduced with the original IBM PC, and was itself superseded by the VGA standard in 1987. In addition to the original EGA card manufactured by IBM, many compatible third-party cards were manufactured, and EGA graphics modes continued to be supported by VGA and later standards.
The IBM PCjr was a home computer produced and marketed by IBM from March 1984 to May 1985, intended as a lower-cost variant of the IBM PC with hardware capabilities better suited for video games, in order to compete more directly with other home computers such as the Apple II and Commodore 64.
MSX BASIC is a dialect of the BASIC programming language. It is an extended version of Microsoft's MBASIC Version 4.5, adding support for graphic, music, and various peripherals attached to MSX microcomputers.

The SV-318 is the basic model of the Spectravideo range. It was fitted with a chiclet style keyboard, which was difficult to use, alongside a combination cursor pad/joystick. This is a disc-shaped affair with a hole in the centre; put a red plastic 'stick' in the hole and with a built-in joystick, remove the stick and it is a directional arrow pad for word processing etc. This machine also had only 16 KB of user RAM, which limited its usefulness. However, this could be expanded via an external peripheral box.
The SV-328 is an 8-bit home computer introduced by Spectravideo in June 1983. It was the business-targeted model of the Spectravideo range, sporting a compact full-travel keyboard with numeric keypad. It had 80 KB RAM, a respectable amount for its time. Other than the keyboard and RAM, this machine was identical to its little brother, the SV-318.
The SVI-728 is the first home computer from Spectravideo that complied fully with the MSX home computer specification. It was introduced in 1984. The design is virtually identical to that of the earlier SV-328, which did not comply fully with the MSX standard.
The Mega PC is a computer manufactured and released by Amstrad in 1993 under license from Sega. It was similar but unrelated to the Sega TeraDrive.
