Date of Release: 6th December 1982
Greenhouse is a fast game where you have to make sure the bugs don't kill the flowers. You operate a Fumigator up and down the ladder spraying the bugs as they emerge. On the top screen Inchworms try to eat the flowers and on the lower screen spiders attack the flowers.
Game B requires more coordination, technique and timing.
Highest possible score is 999. When the score reaches 300 any misses will be erased. If there are no misses, scores are awarded double points until a miss is scored.
Cheats and tricks:
Remember there is no limit on how many times the spray gun can be used, so USE it. The only way you can kill a spider is by spraying it nearest to the flower. When there are no spiders on the screen and you spray, spiders appear at approximately 1-second, slow speed.
On the lower screen you get 1 point when a spider takes a step backwards and
3 points if you kill the spider.
When a spider or inchworm reaches a flower 1 miss is scored. The attacked flower withers and dies. With 3 misses (shown by 3 dead flowers in the upper screen right bottom corner), the game is over.
If you hold in Game A or Game B key the highest previous score will be displayed. If the unit is left as it is after game is over, time display will appear in about five minutes. A game is not interrupted even if TIME key or other game keys are depressed during game playing. Pressing ACL switch or removing batteries erases high score from memory.
Issue Differences (click to enlarge pictures)
The table will show how to tell the different Issues that were made:
The battery covers seem to have a number on the back, but they seem to vary a lot and I won't even speculate what the difference is.
