Syntax 2001 / The Light Circle — Germany, founded 1986

CSDb catalogues this under The Light Circle (TLC) rather than Syntax 2001 — suggesting the two names refer to the same group or closely allied operations. Flash coded the intro, the same member who coded #494 TLC-02, confirming the connection. The charset is credited to Jon Hare, who would later achieve fame as co-founder of Sensible Software — creators of Sensible Soccer and Cannon Fodder. Released on 18 May 1987, this places it in the early growth period of the German cracking scene. The Light Circle was a German group founded in 1986, and the use of the Syntax 2001 label may represent a sub-brand or an earlier identity. The intro runs silent — relying entirely on its visual presentation and scrolltext to make an impression. Hare's charset work predates his commercial career and represents an early connection between the cracking scene and the professional games industry.
