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