AmigaOS 3.1 turns 15 today (the 6th), judging by the datestamps on the disks.
Interestingly, the dates in the version strings of individual files are mostly from early 1993 - this would coincide with development of the 4000T as well. I wonder what the OS group was up to between then and the bankrupcy? Probably laid off, unfortunately...
So in case any former 3.1 developers are reading, thanks for this very important release of our favorite OS!
