Knight’s Tour

Tags: Game

A version of the classic Knight’s Tour puzzle: move a knight with regular knight’s moves so that it visits all 64 squares of the board. The game has a Demo/Solution mode in which the computer starts from the square where you started and gives you a quick look at a solution.

Written by Eric Boisvert for the first issue of Byte Power, August 1986, where the magazine lists it as a strategy game loading as KNIGHTS in 1 minute 45 seconds.

Program Analysis

The tape file is an 18,053-byte BASIC program whose real content is machine code in the REM at line 0. Line 1 starts it with RANDOMIZE USR 28718 unless system variable 23681 is 0, in which case line 2 lists the save line instead. The machine code has not been disassembled, so the description above comes from the magazine.

As with every Byte Power program, the copy instructions in the magazine say to POKE 23681,0 before loading; the program then stops after loading instead of starting, and RUN 9999 saves a personal backup.
