bioform: BobBlusoe, where did you purchase Pegasus Prime? Just on Ebay, or is there a specific place that has stockpiled copies? Your help would be greatly appreciated, as I am keen on trying it out. I highly doubt it would ever appear on GOG, since it would require jumping through too many hoops to get it running on a Windows PC from just a smooth packable executable.
As for the original version, Turbo, it is certainly more possible to see it on GOG, though something would need to be done about the 64bit incompatibility. I believe specific workarounds have been found for other games here though, for those that were originally 16-bit applications.
I bought it on Ebay for $40.00 including shipping. It came unopened in a very nice old fashioned big box. The game discs themselves were in two standard two-cd jewel cases.
