Which came first? I am pretty sure it was computer accounting systems.
Which is older, the oldest continuously supported operating system, or the oldest continuously supported (computer) accounting system?
- eesmith 4y agoThe oldest computer accounting system was likely LEO - https://en.wikipedia.org/wiki/LEO_(computer) https://en.wikipedia.org/wiki/LEO_(computer), online in 1951 and doing accounts probably by 1955, if not earlier. I believe it predate operating systems by a few years. (Wikipedia claims the first OS was the GM-NAA I/O, produced in 1956.)
