  1. Here's how to play UFO:
  2. You have a stationary missle launcher at the bottom of the screen. You
  3. can shoot in three directions; left diagonal, straight up, and right
  4. diagonal.. using the keys 4, 5, and 6 respectively.. You try to hit
  5. one of two objects flying by.. at apparently varying speeds.. Your
  6. score is displayed on your left, the number of missles you have left
  7. is displayed on your right. (You get 15)..
  8. This game ("UFO") is not new. I have a copy of it from 1977 (!). It
  9. was one of the original CHIP-8 games on the audio cassette that was
  10. included when I bought my first computer, the Finnish-made Telmac
  11. 1800.
  12. It was also the first real program to run under CHIP-48 (it was used
  13. as a test case during the development of the CHIP-48 interpreter). The
  14. reason I have not posted it to the net myself is that I have no idea
  15. about its copyright status. I don't even know where it originated
  16. (RCA, perhaps?).
  17. The cassette that was bundled with the Telmac 1800 contains more than
  18. a dozen CHIP-8 programs. If someone could convince me that these
  19. programs are indeed freely redistributable, the other programs could
  20. also be posted. Otherwise, perhaps this one shouldn't have been.
