I'm working on an old pc (actually 2 machines) that runs medical diagnostic software that uses an internal cassette drive. It's connected to an EISA card. The software requires a hardlock key (dongle) to run. The problem is, I can't get the software to recognize the cassette drive. I've changed the I/O on the card and was able to get a blue screen so I know it see's the card. The drive powers up, all the connections are good, and the drivers are installed with the software. Anyone have any experience or thoughts on this archaic system? Thanks!
