Original CI/CD, circa 2000s and maybe earlier! Here's what we had and we loved it *wink*
Version Control: SVN or CVS
Build Tools: GNU Make, Ant, or Maven
Testing: JUnit for those who actually wrote tests...lol
Deployment: Perl/shell scripts, or just plain FTP and fingers crossed that prod will not come down! WinSCP or filezilla yay!
Bug Tracking: Bugzilla where bugs went to die... sometimes. Lmao.
It may have been rough around the edges, but hey, it got the job done eventually! 😅
