I got a old scaner Mediaon MD90092 without Driver CDs for two Euros from „flohmarkt“. The MD90092 is a OEM Product from Microtek Hompage. I need it to run under Mac OS 10.6.8. So I download the scanpotter_1050.dmg (173.4 MB) from Microtek homepage and installed. It works! Great. And the scanner can not work with meine PC with XP. Strange.
