I recently inherited a bunch of equipment from a family member. This is something from them, so I’m not too sure on the history.

This is a SupraDrive ACSI external hard disk for the Atari ST family with an upgraded 52MB hard disk. Tested to boot up on a 1040 ST.

From what I can tell, the original power supply and fan were removed and replaced with a new, external power supply.

This is an excellent hard disk for the Atari ST range because it comes with a cable attached and it has an ACSI and SCSI port on the rear to daisy chain additional devices - whether ACSI or SCSI.  

This is a 30 year old piece of electronics. That said, no returns accepted and no warranty provided.

Ships UPS ground well packed. Includes integrated ACSI cable and a separate power cord included in the box.  Monitor and computer not included; screens shown to illustrate functionality.
