History

Released
24 August 1990
Group
The USA Team — United States, founded February 1988

A historical retrospective release from The USA Team, an American group founded in February 1988 by The Cyclone. CSDb catalogues this as "The USA Team History," released on 24 August 1990 — a silent presentation looking back at the group's brief existence. The group had a remarkably short lifespan of just four months, dissolving in June 1988. According to CSDb, they renamed themselves Dead on Arrival upon discovering that European groups already used the names USA-Team and Dutch USA-Team. Members included The Cyclone (coder), Mac Maroon (graphician), and The Stalker (coder). Despite their brief existence, they produced five releases including four demos. The retrospective format — published over two years after the group's dissolution — is unusual and suggests lingering nostalgia from former members. Comments on intros.c64.org from "German USA Team" and "Sune / German USA TEAM" confirm a separate European group shared the name, adding to the identity confusion that originally prompted the rename.
