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 buss, thus enabling external units such as ZuluSCSI or SCSI2SD to not require external power.
Comes with all hardware, installation, and usage instructions. No soldering or drilling required.
Works with both the ASR-10 and ASR-88 (not the ASR-X, which is different altogether).
