Some PATA controllers show up as or using SCSI IO protocol. But pure IDE.
Adaptec, ATTO controllers sitting around, from PCI PowerMac and NuBus never seen anything, not on MacGurus that turned me on to UL3S in its day, seen 25 or 50-pin to IDE, PATA - or SATA. Only 68-pin to 50-pin. FirmTek did a lot on ATA and controllers and firmware. And had various products.

If there is was would have been on GraniteDigital

The first SATA drives were PATA with a Marvel bridge to provide the SATA interface. Built into the PCB. Translating SCSI into IDE ?
As I said above, Firewire interface with SCSI like Ratoc was, and $90, but people last yr had trouble now with them. Need OS 9 maybe.
There may have, never saw one, and I still have drives, cases, $200 cable and $75 active term.
As you said, results were mixed.
