SupraDrive SCSI

SCSI Controller for the A500 which connects to the side expansion slot. It was probably also supplied with the additional hard drive unti as shown (came in 20MB, maybe other versions) which connects to the back of the controller and has an on/off switch and uses an external power source via the use of a kettle pliug style lead. The SCSI controller unit itself provides an external 25pin connector however it is unsure if this unit could also hold a hard drive or not, however there is a memory daughter card available for the SCSI controller which provides up to 2MB of RAM.
