Oh trackball, where have you gone? Back in the early 80s, when quarters were plentiful and mall arcades were built to satisfy a young man’s fancy, we’d spend some quality time with this rolly control on games like Bowling, Missile Command, and of course, 1978’s Space Invaders. 55DSL is also down with Taito’s alien kill-fest, and in honor of the game’s 30th anniversary, they’re rolling out a limited edition tee with everyone’s (born before 1975) favorite 4-bit iconography. The Soho store will only have them available from 7 – 9 p.m. on April 30, so get there early…and bring an Atari 2600 to bide your time.
