A lot of Unix command were deprecated and disappeared along the years. This place lists some of them for possible resurrection. These lists are based on manual page contents comparisons (so there might be errors).
Another source is the history of documented Unix facilities, "a timeline visualization, a curated data set, and a repository detailing the evolution of 15,596 unique documented facilities (commands, system calls, library functions, device drivers, etc.) across 93 major Unix releases tracked by the Unix history repository".
When the manual page is not enough for reimplementation (that is to say quite often), you can check the original command source code in The Unix Tree.
Interesting commands to reimplement are presented in bold characters.
