- the_only_law 6y agoI recall reading on HN a while back that a modern z/OS mainframe can run unmodified System/360 binaries.
- gnufx 6y agoWell, there was the shocking news here not long ago that some OS\360(?) backwards compatibility had been dropped. What's the world coming to. Relevant to Fortran, there's a version of ESSL that I recall on OS\370 now for POWER9 (and doubtless 10). Scientific subroutine libraries are arguably the best example of the re-use beloved of those who haven't seen their OOP code last decades.
- 1996 6y agowine can also run unmodified windows binaries
- the_only_law 6y agoYes and if those windows binaries were from a platform from over 50 years ago then perhaps your snarky quips would come off as intelligent.
- 1996 6y agoWindows 3.1, released on April 6, 1992 - so only 29 years old. My bad, the 21 years difference must be important (somehow?)
