In the late 1970s, a programmer writing code for Cadillac cruise control and digital dashboard displays walked into a bar, saw a Space Invaders cabinet, and realized it ran on the same MOS Technology 6502 chip she used every day. This episode follows Dona Bailey, born in Little Rock in 1955, who finished a psychology degree with three minors by 19, earned a master’s in math, joined General Motors in 1978, and then left for Atari’s coin-op division in 1980 as its only woman designing stand-up arcade machines.

We trace how she passed over a notebook full of laser and spaceship concepts to pick a bug winding down the screen, partnered with Ed Logg on Centipede, chose a trackball over a joystick to lower cognitive load, and kept a technician’s accidental CRT miscalibration as the game’s signature pastel palette. Centipede became Atari’s second best-selling coin-op and one of the first to draw a significant female player base. We also cover the unfinished Weather War, her time at Videa and the unreleased Glass Bead Game, her exit from the industry by 1985, her return to academia for two more master’s degrees, her teaching at the University of Arkansas at Little Rock, her 2013 Women in Gaming Lifetime Achievement Award, and her screenplay Sunnyvale.

• Why fluency in 6502 assembly worked as a universal passport across industries in the 1970s
• How a psychology background reframed shooting aliens into swatting a garden pest
• Why an analog trackball feels more natural than an eight-way joystick for new players
• How the hardware ceiling of the 6502 contributed to burnout on ambitious projects
• Why instructional design and game design draw on the same skill set
