Dr. Loomis,
All I can say about all the cards I have is this. When I received the package, one of the cards was in slot 2 and the other two cards were in their little, cheap, Chinese cardboard boxes. I experienced a thought! Why not mount them in slots 3&4 to see if the 4800 would recognize them? I don't know what it means exactly but, they were. I have no reason to believe they wont function as they should. On the contrary, of the two cards, the one I prepared to send you, if you want it, looks as though it was never mounted, judging by the lack of marks on the contacts and around the mounting holes. That is all I can tell you. I don't know what these cards can do, I don't know their worth nor can I know how to verify their functionality.
I am in Ontario Canada.
