Up for sale, one used Opus 150. This is the pc board version, not the one in the metal case. Bought it new a while ago, used it briefly with a M10000 board. Upgraded motherboards and could no longer use it. It's been sitting idle for quite some time and I no longer have a mini-ITX board to test it with so I can't make any guarantees about it. But it was working fine the last time I used it (almost a year ago).
I have the cables to go with it and that's it. The manual is available at www.opussolutions.com
Asking $160 shipped in the lower 48 states. I'm not usually available until the evenings to respond to pm's, so I'll get back to people in the order they respond.
I think it's wrong that only one company makes the game Monopoly.
