Castor Cracking Group (CCG) was a demo group from Sweden, and were active on the ZX Spectrum during 1986–1988.[1][2][3] They were one of the first groups for the ZX Spectrum with their release of Castor Intro early in 1986.[4]
Originally they named themselves after Castor in the constellationGemini, but despite having "Crack" in their name, they actually (at least according to themselves) never cracked any software.[4]
Technically, their demos were not very advanced – they even programmed many of them in BASIC and compiled the result for release.[4] However, their significance lies in their early entry onto the scene.
UK Lead
UK Lead was a label used by Castor Cracking Group for the more "serious" projects. The only two projects released were Spectrum Juggler and 99Y.
