A while ago, I obtained one of these, and have successfully hooked it up to the printer port on (one of) my Linux boxen. It works quite well, and I didn't need to change any software to get it functional. The adapter is housed in a small DB-25 to DB-25 patch box goodie (with the help of a 7400 gate). No problems here (if you desire details, please contact me off list). My problem is that I don't have a proper chad box for this nice punch. It is a clear plastic box that clips over the front of the punch and holds the chad. My temporary solution is to have a plastic bag with some cable ties to the "exit port". While this "works" it isn't ideal. So, I'm looking for a chad box for one of these. Any leads would be helpful. Thanks.
