machine not able to talk correctly to feeder via the data bus ,so may probably bad contact
1-) check that all socket IC was properly seated on the PCB under the Feeder , it may move in shipping
2-) scrub a pencil eraser on the card edge contact ,and ideally put a drop of Stabilant 22A on it
did it mag that was whit the 4000$ machine on ebay ?
have fun ..
Thanks for the info, the card connector is very clean and I've tried it in a few slots. I'll check the IC sockets, that's a good thought. Doesn't seem to even try to read the magazine, just fails very quickly. No I couldn't get hold of the ebay seller with the $4k machine to discuss shipping so had to leave that one! Thanks for that software link by the way...
