automatic remind programs

Forgive the group, but this is a followup.  My poor System V (a Unix PC 7300)
does not even have such goodies as "calendar", or even "at" for that matter.
Is this an example of unbundling or are things like "at" not System V but
just the legendary Unix 7.  It would be very nice to have a pseudo batch
queue routine like "at", cron and crontab are a bit tedious for my naive Unix
abilities.
  Flame me if you will but my perverse curiosity on this matter causes me to
perhaps mis-post.
Cheers,
