TC^3 SCSI Controller FAQ Q. How many SCSI devices can the TC^3 handle?
A. In our test lab, we have had up to 6 SCSI devices hooked up to the TC^3 on a CoCo 3; however, the TC^3 is capable of addressing up to eight SCSI devices (IDs 0-7). Normally SCSI controllers are assigned ID 7, but the TC^3 doesn’t take up an ID, so you can actually have 8 different devices on the bus. Whether or not that’s practical, we’ll let you decide.
