It's unknown if Interton designed and produced the Interton VC 4000 within their own rights, or if they were sold the rights to design and produce it. This is because many other foreign brands have produced "clones" of this system in the preceding years.
The Interton VC 4000's power comes from a Signetics 2650 CPU (which is the same as an Arcadia 2001) and a Signetics 2636 gaming controller. Both controllers contain a 12-button keypad, two fire buttons, and a joystick. Inside the systems control panel, there are four different buttons. The ON/OFF switch, RESET, SELECT, and START.[5]
Released versions
The console was produced by different companies and sold with different names. Not every console is compatible with others due to differences in the shapes and dimensions of the cartridge slots, but all of the systems are software compatible.[6]
In the article about the 1292 Advanced Programmable Video System, there is a table with all the software-compatible consoles grouped by compatibility family (due to the slots).
