[ OP-51 1982 ]

The station helper on the upper screen catches drops of oil from a leaking pipe. Once caught, he needs to go out onto the verander [on lower screen] and empty the bucket into his bosses oil drum. Missing a drop from the pipe or missing the bosses oil drum loses a life. Game is unique in having 4 lives [2 misses on top and 2 misses on bottom screen] and has good playability, quite a classic.
