I did find what appeared to be two versions of this dispenser online, with different electronics.
If the counter is an issue, it may be just a matter of routing the output to the LED to the input for the reset button. Light goes on and it thinks the button's been pressed. Might need a simple transistor switch to reverse the polarity, I don't know.
I wish I had one to experiment on now. And I am kicking myself remembering all of these I've seen at garage sales for $1.00 or less. One had four for sale.
