Hi Jim,
short version: Yes, I can confirm existence of such a software and I'd be highly interested in a copy. Of course I can offer digitizing it ;-) longer version: I am preserving various Rolm (later Loral) 16 bit machines which are hardened, military machines widely comaptible to the DG hardware (1602 compatible to Nova and MSE14/Micro is the hardened Eclipse). If interested, have a look at my logbook... http://www.baigar.de/TornadoComputerUnit/TimeLine.html#HDDsim ...datecodes 10/20/2014 to 12/15/2014 and 2/3/2015 to 2/28/2015. Together with two friends (both maintaining a 1602B and native DG hardware) we built a harddisc simulator to run advanced software (e.g. RDOS). During my efforts I rescued some paper tapes from Rolm (diagnostics)... http://www.baigar.de/TornadoComputerUnit/EB-RolmTapes.jpg ...and among these serious, mighty tapes was one labeled "Star Trek 1/2". I digitized it, but without the second part it is of nut much use, so I am sure that such a game existed for DG hardware. From the first tape I can tell, that it is not just the BASIC listing, but native machine code and there is a copyright message dating 1969-1973 ;-)
The tape pile is fanfold about 10" across in a DG box specially made for such use.
On some occasions I had trouble reading the 30+ years old oiled black tapes due to some holes on the folds being obscured at the from debris of the ageing paper... The very best from Germany, Erik.
