They comes in two varieties, 1292 that has external power supply, and 1392 that has internal power supply. Some sources indicate that the 1292 systems are part of the VC-4000 family, while 1392 don:''t.*see Main article: [[1292 Advanced Programmable Video System]]''

It's unclear if Interton really made the VC 4000 from scratch or if they bought the license and design rights and to the processor from Signetics (At the design time owned by Philips) to produce itthe VC 4000, as have many other brands that produced similar systems the following years.
==Technical specifications==
The VC-4000 is powered by a Signetics 2650A CPU (same as the [[Arcadia 2001]]) and a Signetics 2636 Video Controller. The two controllers are composed of a 12-key keypad, 2 fire buttons and an analog joystick. On the control panel of the system, one can find an on/off switch and three buttons: RESET, SELECT and START.
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 consoles are software compatible.

=="Clones"==
All are technically compatible with the VC 4000 but the cartridge slots are different. They are not really "clones" of the Interton, just capable of running the same programs due to similar internals. Games had to be loaded into the internal RAM instead of run straight from the cartridge (this was usually done by pressing on the "Load" button twice). The consoles are grouped by slot compatibility.
