Actually, Sparky67, as I am using version 5.3 of Polacolor for OS9 on a vintage Sprintscan 35plus, it is not at all unreasonable that I would be expected to pay for R and d for software that runs in OSX. Sad to say, Polacolor 6 does not recognise my scanner so I use VueScan which works well in any case and is easier to colour calibrate and requires rather less mouse-ing athletics. I have my doubts about scsi incompatibility in OS 10.2 as the server model comes with scsi cards from Apple. It might be Adaptec which has this problem as this is an old story with their cards.
