History

Released
1992
Code
Double-T
Music
AudioMaster J (Juha-Matti Hilpinen) — "Buzzer"
Group
Red Sector Incorporated [RSI] — Canada, founded 1985

The sixth numbered intro from Red Sector Incorporated, coded by Double-T with music by AudioMaster J — the Finnish composer Juha-Matti Hilpinen, whose "Buzzer" is preserved in the HVSC under his AMJ alias. Released in 1992, this came during RSI's final C64 period before the group fully transitioned to the Amiga platform. Double-T also coded #163 RSI-11, confirming him as RSI's primary C64 intro coder during their later years. RSI was founded in 1985 in Canada, making them one of the oldest North American cracking groups. The choice of a Finnish musician — AudioMaster J — demonstrates the international connections that even North American groups maintained with European SID composers. RSI would become far better known for their Amiga demo work, but their C64 roots produced a substantial catalogue of crack intros.
