Verso: On quarter of a typed sheet of paper, reads: "CDA's new IRMA 3 Convertible is believed to be the first, single handware product to support both the Micro Channel and Personal Computer architectures. The New hardware product for 3270 terminal emulation also has a unique, patent-pending adapter board which supports the direct attachment of either coaxial or twisted pair cabling.
