Here's one we think you'll enjoy.

Dave Hooper submits this program, called VIPER ATTACK, which is, he admits, a first effort in game programming. I am sure most of you will agree that it certainly doesn't appear to be a first effort and that it is a lot of fun to play.

There are still a few refinements coming for VIPER ATTACK. When available, Dave plans to market this program. Because so. of the special niceties, like on-screen scoring, are not included, you can type it in and run it, courtesy of Dave and the RAINBOW.

Pay careful attention to the nasties! There are a number of different kinds, and we think you'll appreciate the graphic detail with which Dave has concerned himself. As he wrote the other day, it can be a frustrating experience trying to get just what you want.

If you want a tape version (tired fingers?) Dave will be able to supply same for $9.95 plus $1.50 postage and handling. The address is 4490 N. Mumford Dr., Hoffman Estates, IL, 60195.

Batch out for the Vipers! Here's the listing:
