WinTrek was for Windows 3.11. If you google it you can find a free download. There is a XP compatible one. Man, this game is hard! I can't even beat it on the easiest setting! Anyone have any tips/tricks? A fun distraction if you are board with solitare! FYI, on the LRS, the three numbers are enemy ships, starbases, and objects. Example: 013, would be no enemys, one starbase, and 3 objects.
