ppt(6) seems to have had an interesting history. It seems to have been mentioned in the V1 manual as ppt(I), seemingly actually doing something related to paper tape. Then it vanished as far as I could tell. In V7, it seems to have found its current form as a game and got documented on bcd(6) (https://man.openbsd.org/UNIX-7/bcd.6); the bcd game itself shipped with V6 already, but had no man page. However, as far as I can tell, V7 shipped only with binaries for ppt(6), not with source code; 4.3BSD-Tahoe was technically the first source code version of it and presumably a rewrite. This patch adjusts the HISTORY section to match these findings.
