Question: Was Elektor TV Games Computer or Exidy Sorcerer sold first?
Context: The Tulip system I was a 16-bit personal computer based on the Intel 8086 and made by Tulip Computers, formerly an import company for the Exidy Sorcerer, called "CompuData Systems". The AY-3-8910 is a 3-voice programmable sound generator (PSG) designed by General Instrument in 1978, initially for use with their 16-bit CP1610 or one of the PIC1650 series of 8-bit microcomputers.  The AY-3-8910 and its variants became popular chips in many arcade games and pinball machines, and were used on, among others, the Intellivision and Vectrex video game consoles, Amstrad CPC, Oric 1, Colour Genie, Elektor TV Games Computer, MSX and Sinclair ZX Spectrum 128/+2/+3 home computers as well as the Mockingboard and Cricket sound cards for the Apple II family. The TV Boy and its successors TV Boy II and Super TV Boy are 1990s handheld TV games sold by many different companies, including Systema, Akor, and NICS, based upon an unlicensed clone of Atari 2600 hardware.  They were widely available across Europe.  In the UK they were most visibly available through Argos.  An improved version of the TV Boy 2, the Super TV Boy, was made by Akor in 1995. Nada Iveljić (4 April 1931 – 6 September 2009) was a Croatian children's writer.  Her work includes eight books of poetry, a short story collection, a novel, over forty books and a series of picture books for children, and several plays, radio and TV games for adults and children. GameKeys are expansion modules made by Jakks Pacific for the purpose of adding games to GameKey-ready entries in their Plug It In & Play TV Games product line. A Namco Plug & Play Game is any of a series of models dedicated to games by Namco which make up a subset of Jakks Pacific's Plug It In & Play TV Games plug & play game system lineup with the exception of the newest one called "Pac-Man Connect and Play" which was handled by Bandai America instead of Jakks Pacific.  They should not be confused with the Japan-only "Namco Nostalgia" pair of plug & play games directly from Namco Bandai Games. The Sorcerer is one of the early home computer systems, released in 1978 by the videogame company Exidy.  It was comparatively advanced when released, especially when compared to the contemporary more commercially successful Commodore PET and TRS-80, but due to a number of problems, including a lack of marketing, the machine remained relatively unknown.  Exidy eventually pulled it from the market in 1980, and today they are a coveted collector's item. The Atari Joystick Controller TV Video Game System was made in 2003 (copyright 2002) in Jakks Pacific's Plug It In & Play TV Games plug-n-play game system lineup. WayForward Technologies, Inc. is an American independent video game developer based in Valencia, California.  Founded in 1990 by technology entrepreneur Voldi Way, WayForward started by developing games for consoles such as the Super NES and Genesis, as well as TV games and PC educational software.  In 1997, they relaunched their video games arm, placing the company as a contractor for publishers and working on a variety of licensed assets. 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.
