Where can I find Drivers to use IOMEGA 35GB REV w/USB?

Ancient History:

I'm selling an old Powerbook G4 w/REV drives and cartridges, but can't find the software to get the computer to recognize the drive. I had Leopard on there and NO trouble using the drive. The new buyer needs TIGER so he can use 09 emulation on a drawing program he uses.

I've searched in vain trying to find uinversal support for a REV USB drive on TIGER, but all I find is OLD software which can only be used with a firewire drive. Lenovo no loner supports the old products. I must have found the software once.

Help!!!!! 😢
