TC^3 SCSI Controller
Documentation FAQ
Full SCSI Support for your CoCo

Never before has the CoCo had this many storage options! SCSI is the way to go on your Color Computer with up to 8 devices supported on a single bus. We've used various size hard drives and even CD-ROMs on this controller with amazing success. 100% compatible with OS-9 (using our SuperDriver software) and BASIC (using our HDB-DOS product). Given the fact that SCSI controllers are harder and harder to find, this is a great product if you want to bring mass storage options to your CoCo.
