The cabinet on the flyer looks like a modified After Burner II cab. Perhaps it was going to be a Max-A-Flex type computer in a cabinet, or was merely an artist's promotional mock-up with an Amiga, Atari ST, IBM PC, CPC, Commodore 64, or Sega Master System inside it. Even the title screen of the console version asks to Insert Coins.
