The IBM 4224 is a 200 to 400 CPS dot matrix printer (usually 18 pin) for use on IBM networks. It sounds like you have the Twinax interface, about 1" in diameter, screw connector, with two pin holes. It is not usable on anything but a twinax network. I bellieve that IBM made 3 versions of varieing speeds in two interfaces. The second interface is a BNC Coax for the 3270 systems. While the networks are over 10 yrs old I doubt the printer is. Paxton
