Description:
This program was written by Tim Hartnell. Tim was one of the most prolific authors and writers for the early personal computers with many books, programs and articles to his name.
This program is from the book "Getting acquainted with your ZX81" (page 20). The following is the accompanying text from the book.
Star-Map creates a galaxy (of sorts) on your TV screen and is an effective display program if left to run for a long time. The program sets up a black rectangle and proceeds to PRINT AT and unPRINT AT stars in this black nothingness.
Tim died of cancer in 1991 after returning from London to Melbourne, and permission has been given by his estate for his programs to be placed in the public domain.
These programs may not be distributed for profit or altered in anyway. They may not be distributed on any CD.
