User programming

An expensive £49 (equivalent to £288.01 in 2025 pounds) Hobby Module was available which gave 6.5 kilobits of user-programmable memory and had a 5-pin DIN socket to allow software to be saved to a cassette tape player. This converted the unit into halfway between a home computer and an ordinary gaming console.

The user had to be familiar with programming in Signetics 2650 assembly language and the unconventional ways and register architecture of the Signetics 2650 processor.

Released versions

The console was produced by different companies and sold with different names. Although all variants have identical computational hardware, changes to the dimensions of the cartridge slot on some variants result in cartridges not always being interchangeable between systems. The following is a table of the console variants grouped by cartridge compatibility.

Games

Although, not much information is known about the release dates of the cartridges, the total number of the games should be 59 (33 games released by Radofin between 1977 and 1978, 19 games for the Interton VC 4000 and compatibles after 1978, and 7 more games released around 1980).
