TRS-80 Star Trek (1979) source

I know I keep going on about Star Trek…actually Super Star Trek. But it holds an important spot in my memory for my early days with computers. It somehow means more to me that I can play the 1979 version than some newer improved versions. Anyhow it appears (I spot checked a few random line numbers) that SUPSTU1A/BAS on floppy sst2.dsk in my 0-MyDisks directory is almost an exact match of Basic Computer Games TRS-80 Edition by David H Ahl (Copyright @ 1979 Creative Computing) pages 161-162. I say almost because sometimes an extra space is in the code. For example in the book…930 GOTO590 but in the disk listing…930 GOTO 590, so a space has been added after GOTO!
