This is a full-featured SCSI interface for your Ensoniq ASR-10. It is fully compatible with the ASR-10, plus has one special feature: it supplies termination power to the SCSI bus, thus enabling external units (such as ZuluSCSI) to not require external power.
Comes with all hardware, installation, and all usage instructions. No soldering or drilling needed!
Works with both the Ensoniq ASR-10 and ASR-88 (not the Ensoniq ASR-X, which is completely different).
