Yes--and IIRC, it used a 50-conductor connection as well. We had some big CDC OEM line printers in the mid 1980s that could be configured for either interface. Before that, in about 1975 we had a Diablo dot-matrix printer (a strange, very loud beast) that used the DP interface. (ISTR that it also used three Rockwell PPS-8s). Memory grows dim with each passing year. --Chuck
