I don't know for specific but they did point out in a couple of the articles that they are running on old mainframes. They say some are 40 years old, but it is unclear whether that is just the software or the hardware or both, wouldn't be unreasonable that it is both IME. Those old IBM machines run forever and generally as long as you keep paying IBM, they will keep supporting you. My guess is these are either the old IBM or HP/Compaq machines of the day, both were popular in government installations. Many state and county governments still have active mainframe machines to this day and they are just as at risk as Nj is. Hell less than ten years ago I had a contract where we had to write EBCDIC files in batches for a as/400 at the county government to process overnight to update county records and we did that from a modern (at the time) web architecture with a SOA layer. We would take the output of the nightly batch processing and in-jest it to update our SQL database for the website every morning. Fun times.
