I've got an OD3210 9-track drive that's been sitting around here for a couple of years. I note that it has a Pertec interface (seems to work) and a parallel port interface. I'm curious about the latter. It appears to be 4-bit each direction, but I don't have a clue as to the protocol or command set. Does anyone have a driver or information about the Overland parallel port interface? Thanks, Chuck
