I've seen KO TF Monopoly boards around Cabramatta - so they do exist.

The actual board is the same quality as other Monopoly boards - made of fairly sturdy cardboard. Similar to most other board games like Scrabble and your fold-out Chess boards. The pieces are made from die-cast metal. The dice are made from transparent red and purple plastic (one is red the other purple) so they look like "glowing" red and purple Energon cubes due to natural light piping. The "Chance" and "Community Chest" cards (called Autobot and Decepticon cards) have their messages 'scrambled' like the 1984-88 tech specs and also comes with a square tech specs decoder framed by a piece of cardboard that is red (Autobot) on one side and purple (Decepticon) on the other. The messages are pretty hard to read without the decoder.

Sounds to me you might have a KO.
