Group
Ikari — United Kingdom, founded July 1987

An early Ikari intro from October 1987 — just three months after the group's founding — already showing the professional multi-role production approach that would define their output. Pal coded while Mad (Marcel Donne) contributed "Dervish D," an original composition preserved in the HVSC. Terry Lloyd provided graphics and Jon Hare — whose charset work also appears in #3 Dynamic Duo and #50 Flash Cracking Group — contributed the charset. The five-person team on a 1987 intro demonstrates Ikari's ambition from day one. Doc Snyder's page preserves the scrolltext. Jon Hare's presence is notable — the same name as the Sensible Software co-founder, though whether this is the same person remains debated in scene circles.
