camtracker trail cameras

I recently was gifted some old Camtrakker MK 8 trail cameras. I don't have an instruction manual and have been fighting to figure these things out. They are out of business and my google-fu doesn't seem adequate to turn anything up. Anybody familiar with these cameras or have a copy of the instructions? For now, my biggest proble is that I can only get the camera to recognize 1 of my SD cards. I have formatted several and the only one it will recognize is an old 1 GB Lexar. Thanks for any info.
