Maybe re-read his question? He was asking, if "all" modern PC's have reset switches, then why do only "most" WOZ games have reset switches. Why don't they all?
Quoted from Pinchroma:
Most woz do have it. Reread the thread.
I don't know anything about WOZ, buy why can't you just go into the CMOS and do a reset instead of pulling the battery etc?
Quoted from pinballinreno:
Even with reset switches, sometimes you have to clear the CMOS. e.g. pull battery and apply the jumper to the 2 clr cmos pins.
