IDT tape drive information

I'm looking at buying an IDT (Innovative Data Technology) tape drive, model TD-1054/INTL. I don't have any information on it other than that. It's a manual thread drive, and appears to be 800/1600bpi. But, what I can't tell from the seller's pictures is the interface. He thinks it's Pertec, but doesn't know. I don't have a formatter board, all my machines are set up to communicate with formatted Pertec drives. It _appears_ to have two 50 pin connectors on the board, but it looks like a couple of the fingers aren't populated. I don't remember ever seeing a Pertec drive like that. (but I could be wrong...) I've emailed the seller asking for a better picture, but I was hoping that someone here might have some knowledge about this drive. Thanks! -Ian
