I believe CDC Cyber series of mainframes were installed in many countries. I knew of at least two, one in the institute that i studied in and another at a bank, both in Calcutta (aka Kolkata), India in late-80's/early-90's.
My first job was implementing a Personnel Information System using Cobol85 on a Cyber 180/840A in the above-mentioned institute. Its OS was named NOS/VE and it had its own system programming language named Cybil. There were racks of manuals which unfortunately i didn't understand much of since i was a noob fresh out of school. A lot of hardware and OS research/advances were first done in the mainframe world before being scaled down and adapted to smaller computers. I wish there were some special courses teaching how hardware/OS/Languages evolved from the beginning so that we can see concretely how a single idea started from simple origins and ended up as the highly complex implementations we have today. History gives you insight which you can never get by reading just the facts today.
