I kind of doubt that, unless they had a version of IBM's IMS for it -- which I find unlikely, though I suppose maybe they had some of those along side real (or compatible) IBM hardware. I worked for Wisconsin DOT from 1975 until 2012. Just before I got there, they had completed their own quite competent DMBS, which was written (in assembler) because IBM's IMS was too inefficient and ADABAS was too expensive. (That DBMS was still running some production when I left, in parallel with DB2 but has since been retired.) They learned IMS had issues when they talked with California, who told them that at any one time a substantial part of their (either Drivers or Motor Vehicle) database was offline at ANY time because it needed reorganization. I did write some COBOL on the IBM 1410 which I worked on while I was a student (COBOL for which was surprisingly capable), DOS/VS, OS/360, MVS, and so on. I found it to be: - Very cumbersome and visually inefficient - Error prone - Harder than heck to read So, mildly better than Assembler, but I'll take C and its descendents over COBOL any day for anything. Indeed I was responsible for introducing C into our organization in the 1980's -- I was exposed to it, and UNIX just about the same time I went to work for WisDOT. JRJ
