CP/67 had arrived with 1052&2741 terminal support and auto-terminal ident, capable switching terminal type scanner type for each port. Univ. also had TTY33&35 and I add ASCII support integrated with auto-terminal type. I then want to have single dial-in number (hunt group) for all terminals. Didn't quite work, IBM had hard-wired line speed ... so we start a clone terminal controller. Build a IBM channel interface board for Interdata/3 programmed to emulate IBM controller with the addition for auto-baud. Then upgraded with Interdata/4 for channel interface and cluster of Interdata/3s for port interfaces. Interdata (and later Perkin-Elmer) sell them as clone controllers. https://en.wikipedia.org/wiki/Interdata https://en.wikipedia.org/wiki/Perkin-Elmer#Computer_Systems_Division ... and four of us are written up responsible for (some part of) IBM clone controller business. Other trivia, when tty/ascii port scanner for 360/67, it came in "Heathkit" box. Before leaving for Boeing. I modified HASP for MVT18, with CRJE implementation, including editor that implemented CMS edit syntax (environments were so different that couldn't reuse any code). -- virtualization experience starting Jan1968, online at home since Mar1970
