This is just awesome!
As an "old dude" I played the original text based Star Trek on microcomputers of the late 70's and early 80's and it has long had a special place in my heart! I also played Star Trek 25th anniversary on my 486 in the early 90's.
This inspires me to do something similar on some of the "modern retro computers" that are out now like the Color Maximite 2, Commander X16 etc....
Amazing work!
