This is a quick note that hopefully will save a few people some of the time I just spent. I use a an old Mac G4 as a development server here to test ideas before they go live. It is basically a mirror of the software on the web server run by webfaction: django, Apache 2.0, mod_python, etc. It also has an old Adaptec SCSI card, which makes it a special sort of relic and the only gear that can talk to an the Imacon scanner here. The main drive failed yesterday so I took the opportunity to upgrade the system software to OS X 10.5 (leopard), which as I quickly learned doesn't have drivers for the SCSI card effectively turning the Imacon into a paper weight. All indications on the web suggested that the only ghost of a chance was the Ratoc Systems FR1SX FireWire to Ultra SCSI Converter, which has reportedly worked for some but not everyone—SCSI being one of those black arts closer to witchcraft than computer science. Loath to spend $110 on something that might or might not work, I thought I'd try everything else first. Apadtec's website suggests the card is not supported with 10.5. Then I found this: Mac OS X Driver, version 1.1. I downloaded, installed it, and unbelievably it worked.
