The back of the Atari ST itself merely labels the port "Hard Disk", making the term "ACSI" rather obscure at the time. A company called Supra, as well as Atari themselves, both made ACSI hard drives. Akai therefore called their compatible interface boards "Atari/Supra", to helpfully suggest which brands of hard drive were compatible with them.
