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 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.
