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.
