Identity and conversion format
The Open Pinball Database identifies Sexy Girl as an Arkon solid-state, four-player machine with alphanumeric displays and records it as a conversion kit.
Arkon's service manual explains that the playfield and projector were sold separately as a conversion kit for electronic Bally pinball machines. It specifically states that installing the Sexy Girl playfield in Bally's Playboy required no changes.
Projection system
The machine combines conventional pinball hardware with a cassette-based projection system. The projector contains optics, film, control circuitry and its own power supply. Its replaceable cassette holds approximately 200 images.
Playfield targets control the film transport, advancing the projected image during play. The projector lamp is also governed by playfield bonus lamps and the game-over signal.
Hardware
Arkon's manual says the machine uses Bally electronics with 43-volt coils, while its mechanical parts follow Gottlieb-style mechanisms. The manual also provides instructions for using Bally program hardware when fitting the conversion to compatible machines.
