Question: Do both Sega and Altair 8800 fall into the category of electronics?

Heathkit's H8 is an Intel 8080-based microcomputer sold in kit form starting in 1977.  The H8 was similar to the S-100 bus computers of the era, and like those machines was often used with the CP/M operating system on floppy disk.  The main difference between the H8 and S-100 machines was the bus; the H8 used a 50-pin bus design that was smaller, more robust and better engineered electrically.  The machine also included a bootstrap ROM that made it easier to start up, including code for running basic input/output and allowing input through a front-mounted octal keypad and front panel display instead of the binary switches and lights used on machines like the Altair 8800.  The H8 was a successful design but required a separate terminal to be truly useful; Heathkit introduced several terminals as well.  A successor model, the "All-in-One" Heathkit H89, combined a Z-80 processor board and a floppy disk drive into the cabinet of an Heathkit H19 terminal.  This model also was sold in fully assembled form as the WH89.  These were later sold by Zenith Electronics with their name on the front as the Zenith Z-89. <SEP>  Sega developed and manufactured numerous home video game consoles from 1983 to 2001, but after financial losses incurred from its Dreamcast console, the company restructured to focus on providing software as a third-party developer. Sega Games Co., Ltd. (Japanese: 株式会社セガゲームス , Hepburn: Kabushiki gaisha Sega gēmusu ) , originally short for Service Games and officially styled as SEGA, is a Japanese multinational video game developer and publisher headquartered in Tokyo, Japan, with offices around the world.  Sega remains the world's most prolific arcade producer, with over 500 games in over 70 franchises on more than 20 different arcade system boards since 1981. <SEP>  Interest grew quickly after it was featured on the cover of the January 1975 issue (published in late November 1974) of "Popular Electronics", and was sold by mail order through advertisements there, in "Radio-Electronics", and in other hobbyist magazines.  The designers hoped to sell a few hundred build-it-yourself kits to hobbyists, and were surprised when they sold thousands in the first month.  The Altair also appealed to individuals and businesses that just wanted a computer and purchased the assembled version.  The Altair is widely recognized as the spark that ignited the microcomputer revolution as the first commercially successful personal computer.  The computer bus designed for the Altair was to become a "de facto" standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC. The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. <SEP> Microsoft is an American public multinational corporation headquartered in Redmond, Washington, USA that develops, manufactures, licenses, and supports a wide range of products and services predominantly related to computing through its various product divisions.  Established on April 4, 1975 to develop and sell BASIC interpreters for the Altair 8800, Microsoft rose to dominate the home computer operating system market with MS-DOS in the mid-1980s, followed by the Microsoft Windows line of operating systems.  Microsoft would also come to dominate the office suite market with Microsoft Office.  The company has diversified in recent years into the video game industry with the Xbox, the Xbox 360, and the Xbox One, as well as into the consumer electronics and digital services market with Zune, MSN and the Windows Phone OS.
