Key Clicker Routine

If you have a newer Apple with the silent keyboard, Don Williams has written a short and sweet machine language routine to solve your problem. 0300:  48              PHA 0301 : A9 20        LDA #$20 0303: 8D 30 CO   STA $C030 0306: 20 A8 FC    JSR $FCA8 0309: 8D 30 CO   STA $C030 030C: 68              PLA 030D: 4C 1B FD   JMP $FDIB 0038: 00 03 Once you store the address ($0300) in location $38 and hit return, your keys will click merrily away until you hit reset. To restart the routine, reenter the address. •A minor modification of this routine will give you a slow list (with tones) feature. Change the JMP and 030D to FOFD and store the address in $36. The value stored at $0302 may be increased for a slower list.
