Three games that are sought after.

Black Knight is plentiful and a legendary player

Pharaoh is a very good player. Artwork is excellent.

The third game was Jungle Lord. These three were operated in Australia. Solar Fire were not produced in enough numbers to make it to Australia. This is when the SYS7 platform production runs tapered. I've heard of one container game that was completely trashed. That's about it. i'm sure someone will have one in a collection, but it would be rarer than say a Fathom.
