I purchased these wholesale in the 1980s. Timex boxed them one dozen of a single title per box, and then, if you were a large retailer like Kroger supermarket, they would package 12 boxes in a master carton of a gross. I selected 12 different titles that I had full boxes for and then took all the cassettes out of the boxes and repacked them putting one of each title in those original boxes. I prepared labels showing the titles and pasted them to the end, top, and inside flap of the boxes for easy identification. ( I happen to enjoys arts and crafts.)These are the 12 titles included. One runs in 2K, but all the others require 16K.The Flight SimulatorThe Stock Option AnalyzerBackgammonCritical Path AnalysisThe Cube GameThe Coupon ManagerThe Checkbook ManagerMixed Game Bag ISupermathChessMoney Analyzer 1The Gambler The 12 tapes weigh 1lb 12oz, or 796 grams.
