I have a copy of this game if anyone would like it. I also have gotten a hold of one of the developers of the game and can get you 100% confirmation that it is abandonware. To check it out click my link below. Also I have an update to OMF 2097. It has the updated version that lets you play online, and I'll have to dig up an old school RPG I made too. Wow I love this place.

Also I have a copy of Sanitarium if you are interested. The game isn’t DOS era but the company is no longer around and it is very good. I can upload that as well if you like. I'll have to go though my library to see if I have anything you don't.
