Here is the schematic: PC SPK: ------------------| /| / --/ | 100 \ <-------------| | SPKR OHM / |------| | POT \ | --\ | / | \| PC GND: ------------------|--------| An audio taper potentiometer would be "proper" here, but linear pots are easier to find at 100 ohms and work fine. Too bad IBM didn't put a DAC in front of the speaker, square waves are kind of limiting. ^ ^ Forrest Cook - Beware of programmers who carry screwdrivers - LB /|\ /|\ cook@stout.ucar.edu (The preceeding was all my OPINION) /|\ /|\ {husc6|rutgers|ames|gatech}!ncar!stout!cook /|\ /|\ {uunet|ucbvax|allegra|cbosgd}!nbires!ncar!stout!cook
