Precomputers

We worked with encrypted communications, in an atmosphere of secrecy with wheels and codes and what was then considered advanced data processing equipment (precomputers, of course).

There should be some kind of law that no one is allowed to have visions past the age of fifty, especially if said person used to be a car mechanic, precomputers.

The only caveat is if you bought something pre-computers, or inherited stocks pre-computers, then if you actually have that purchase date, you can keep it.
