A quick entry for a title where the 3rd title in the series seems to be out there (http://www.gb64.com/game.php?id=17549), but the first two are completely missing.
The first two versions did exist, as it was clearly advertised in the press at the time. All three games were graphic text adventure games.
Can you help us find the first two editions to complete the trilogy?
