2400 A.D. cheat codes:
Get the East Zone checker robot into the stairwell behind the FA74 passcode
Spider gives you at the Novue Apartments. Once it is there, attack it, then
collect the credits from it. Climb down the stairs, heal, and return. It will
respawn after about 50 moves and the process can be repeated.
Note: Other enemies cannot reach you at that location.
If your IQ is at least 15 when starting the game, enter the transport in the
