Written for: Sherwood Forest ][ and Sherwood Forest /// =-----------------------------------------------------------------------------= This weeks topic: Homeword =-----------------------------------------------------------------------------= Homeword, by On-line systems, is a fantastic word processor, which is both well doccumented and easy to use. It is the first word processor, to my knowledge, to incorporate icons at all menu prompts. It comes with a cassette which helps in teaching you how to use the program. The de-protection is fairly simple, and like the Xerox series, requires only a sector editor. If you do not know how to use the Inspector sector editor, the docs can be found on Sherwood Forest ///. => Read Track 10, Sector A. => Change byte $00 from $CE to $60 => Write Track 10, Sector A back to disk This does the exact same thing as the Xerox de-protecting. Note that $CE stands for DEC (DECrement accumulator). By replacing it with $60, RTS (ReTurn from Subroutine), you are replacing the first byte of the nibble count routine, and telling it to jump back to the main program, without executing the nibble count at all. If the nibble count were to be executed the program would crash, re-boot, or freeze up. =-----------------------------------------------------------------------------= _________________ | | | Happy Cracking! | | High Technology | | The Apple Mafia | |_________________| - End of File -
