I have it somewhere around here. In order to make it work I booted from RAD: with the floppy it came with, worked fine. I will dig through my archives and give you the exact setup or will post the whole boot disk. It was a great game though. Just to confirm I have the right game in mind, it was the duplication of FASA Battletech with the overhead Hex perspective, just like the board game with the seperate warrior, unit, and mech editors.
Have a great day!
