I am scratching my head over making some legacy mass storage accessible from my M3 MBP to recover the data from old tapes and HDD drives for forensic purposes. All of the legacy devices have SCSI interface. I currently see two potential ways forward. One would seem to be a SCSI host controller in a PCIe enclosure hooked up via Thunderbolt. That would require usable drivers or out-of-the-box support in macOS, both of which seem unlikely to me with current macOS versions however. The other route I could see is using an EZ-USB eval board plus some glue circuitry (e.g. differential line drivers) to approximate a SCSI PHY. I could then implement software on the EZ-USB to proxy the SCSI communication from the devices to a UAS driver in macOS. However easy or complex implementing this may end up being in reality, it depends on the availability of UAS support in current macOS. Hence my asking the question.
